Eliminate CXXConditionDeclExpr with extreme prejudice.
...
All statements that involve conditions can now hold on to a separate
condition declaration (a VarDecl), and will use a DeclRefExpr
referring to that VarDecl for the condition expression. ForStmts now
have such a VarDecl (I'd missed those in previous commits).
Also, since this change reworks the Action interface for
if/while/switch/for, use FullExprArg for the full expressions in those
expressions, to ensure that we're emitting
Note that we are (still) not generating the right cleanups for
condition variables in for statements. That will be a follow-on
commit.

Clean up the AST for while loops and fix several problems with
...
cleanups for while loops:
1) Make sure that we destroy the condition variable of a while statement each time through the loop for, e.g.,
while (shared_ptr<WorkInt> p = getWorkItem()) {
// ...
}
2) Make sure that we always enter a new cleanup scope for the body of the while loop, even when there is no compound expression, e.g.,
while (blah)
RAIIObject raii(blah+1);

Introduce cleanup scopes for "if" statements in two places:
...
- Outside the "if", to ensure that we destroy the condition variable
at the end of the "if" statement rather than at the end of the
block containing the "if" statement.
- Inside the "then" and "else" branches, so that we emit then- or
else-local cleanups at the end of the corresponding block when the
block is not a compound statement.
To make adding these new cleanup scopes easier (and since
switch/do/while will all need the same treatment), added the
CleanupScope RAII object to introduce a new cleanup scope and make
sure it gets cleaned up.

Eliminate QualifiedDeclRefExpr, which captured the notion of a
...
qualified reference to a declaration that is not a non-static data
member or non-static member function, e.g.,
namespace N { int i; }
int j = N::i;
Instead, extend DeclRefExpr to optionally store the qualifier. Most
clients won't see or care about the difference (since
QualifierDeclRefExpr inherited DeclRefExpr). However, this reduces the
number of top-level expression types that clients need to cope with,
brings the implementation of DeclRefExpr into line with MemberExpr,
and simplifies and unifies our handling of declaration references.
Extended DeclRefExpr to (optionally) store explicitly-specified
template arguments. This occurs when naming a declaration via a
template-id (which will be stored in a TemplateIdRefExpr) that,
following template argument deduction and (possibly) overload
resolution, is replaced with a DeclRefExpr that refers to a template
specialization but maintains the template arguments as written.

reimplement codegen for indirect goto with the following advantages:
...
1. CGF now has fewer bytes of state (one pointer instead of a vector).
2. The generated code is determinstic, instead of getting labels in
'map order' based on pointer addresses.
3. Clang now emits one 'indirect goto switch' for each function, instead
of one for each indirect goto. This fixes an M*N = N^2 IR size issue
when there are lots of address-taken labels and lots of indirect gotos.
4. This also makes the default cause do something useful, reducing the
size of the jump table needed (by one).

Fix for PR4721: adjust CodeGen and ASTContext so that we have a
...
consistent model for handling size expressions for VLAs.
The model is essentially as follows: VLA types own their associated
expression. In some cases, we need to create multiple VLA types to
represent a given VLA (for canonical types, or qualifiers on array types,
or type merging). If we need to create multiple types based off of
the same VLA declaration, we use the new refcounting functionality so they can
all own the expression. The VLASizeMap in CodeGenFunction then uses the size
expression to identify the group of VLA types based off of the same original
declaration.
I'm not particularly attached to the VLA types owning the expression,
but we're stuck with at least until someone comes up with a way
to walk the VLA expressions for a declaration.
I did the parallel fix in ASTContext for DependentSizedArrayType, but I
haven't really looked closely at it, so there might still be issues
there.
I'll clean up the code duplication in ASTContext in a followup commit.

Create a new TypeNodes.def file that enumerates all of the types,
...
giving them rough classifications (normal types, never-canonical
types, always-dependent types, abstract type representations) and
making it far easier to make sure that we've hit all of the cases when
decoding types.
Switched some switch() statements on the type class over to using this
mechanism, and filtering out those things we don't care about. For
example, CodeGen should never see always-dependent or non-canonical
types, while debug info generation should never see always-dependent
types. More switch() statements on the type class need to be moved
over to using this approach, so that we'll get warnings when we add a
new type then fail to account for it somewhere in the compiler.
As part of this, some types have been renamed:
TypeOfExpr -> TypeOfExprType
FunctionTypeProto -> FunctionProtoType
FunctionTypeNoProto -> FunctionNoProtoType
There shouldn't be any functionality change...

IRgen improvements on unreachable code:
...
- Split out "simple" statements which can easily handle IR generation
when there is no insert point. These are generally statements which
start by emitting a new block or are only containers for other
statements.
- This fixes a regression in emitting dummy blocks, notably for case
statements.
- This also fixes spurious emission of a number of debug stoppoint
intrinsic instructions.
Remove unneeded sw.body block, just clear the insertion point.
Lift out CodeGenFunction::EmitStopPoint which calls into the
CGDebugInfo class when generating debug info.
Normalize definitions of Emit{Break,Continue}Stmt and usage of
ErrorUnsupported.

Make emission of 'if' conditions much more sophisticated when we
...
have a condition that is an &&/||. Before we used to compile things like this:
int test() {
if (x && y) foo(); else bar();
}
into:
%0 = load i32* @x ; <i32> [#uses=1]
%1 = icmp ne i32 %0, 0 ; <i1> [#uses=1]
br i1 %1, label %land_rhs, label %land_cont
land_rhs: ; preds = %entry
%2 = load i32* @y ; <i32> [#uses=1]
%3 = icmp ne i32 %2, 0 ; <i1> [#uses=1]
br label %land_cont
land_cont: ; preds = %land_rhs, %entry
%4 = phi i1 [ false, %entry ], [ %3, %land_rhs ] ; <i1> [#uses=1]
br i1 %4, label %ifthen, label %ifelse
ifthen: ; preds = %land_cont
%call = call i32 (...)* @foo() ; <i32> [#uses=0]
br label %ifend
ifelse: ; preds = %land_cont
%call1 = call i32 (...)* @bar() ; <i32> [#uses=0]
br label %ifend
ifend: ; preds = %ifelse, %ifthen
Now we turn it into the much more svelte code:
%0 = load i32* @x ; <i32> [#uses=1]
%1 = icmp ne i32 %0, 0 ; <i1> [#uses=1]
br i1 %1, label %land_lhs_true, label %ifelse
land_lhs_true: ; preds = %entry
%2 = load i32* @y ; <i32> [#uses=1]
%3 = icmp ne i32 %2, 0 ; <i1> [#uses=1]
br i1 %3, label %ifthen, label %ifelse
ifthen: ; preds = %land_lhs_true
%call = call i32 (...)* @foo() ; <i32> [#uses=0]
br label %ifend
ifelse: ; preds = %land_lhs_true, %entry
%call1 = call i32 (...)* @bar() ; <i32> [#uses=0]
br label %ifend
ifend: ; preds = %ifelse, %ifthen
Note the lack of a phi node.
This shrinks the -O0 .ll file for 176.gcc/expr.c from 43176 to 40267 lines.

Rework IRgen invariant w.r.t. current insert point.
...
- EmitStmt is no longer required to finish with a current insertion
point defined (i.e. it does not need to make dummy
blocks). Instead, it can clear the insertion point in the builder
which indicates that the current insertion point is unreachable.
- CodeGenFunction provides HaveInsertPoint and EnsureInsertPoint
which respectively test if there is an insert point and ensure an
insertion point exists (by making a dummy block).
- Clearly mark functions in CodeGenFunction which can be called with
no insertion point defined. Currently this is a limited set, and
EmitStmt simply EnsureInsertPoint()s before emitting subsequent IR.
Remove EmitDummyBlock, which is no longer needed. Clients who haven't
already cleared the insertion point (typically via EmitBranch) can do
so by hand.
Remove isDummyBlock, which has effectively been renamed to
HaveInsertPoint.
The main thrust of this change is that we no longer have create dummy
blocks just to destroy them a short time later in EmitBlock in the
common case that there is no unreachable code following something like
a goto.
Additionally, this means that we are not using the hokey condition in
isDummyBlock that a block without a name is a dummy block. Guess how
well that works when we never emit block names!
