Fix support for _Bool bitfields. The issue is that the bitfield width

used for _Bool is not the same as the primitive width (which for _Bool

types consistent. The EmitLValue changes make sure that the pointer is
of an appropriate type for loading the bitfield.
This isn't perfect, but it's an improvement, and getting everything
right depends on actually laying out structs in an ABI-compliant way.

Sema-based fix for PR2334. The issue is that even if the two sides of

the condidtional have compatible types, they are not necessarily the

...
in Sema::CheckFunctionCall:
http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20080512/005706.html
The bug was that the logic from the helper methods used by CheckFunctionCall
were being inverted (a subtle bug). This would cause the parser to discard
any valid AST nodes involving several builtins (see patch).
This removes the last regression failure I'm seeing in the test suite: Analysis-Apple/NoReturn.

Problem:
In the recently refactored VisitDeref (which processes dereferences), we
were incorrectly skipping the node just generated for the subexpression
of the dereference. This was a horrible regression.

TranslationUnit now owns IdentifierTable, TargetInfo, and Selectors objects
...
when it is constructed via deserialization. This is done by recording a flag
indicating that this is the case, and it deletes these objects by getting
the references stored in the ASTContext object. This fixes some memory
leaks that occurs when we deserialize translation units from bitcode files.
The rationale between having TranslationUnit sometimes own these objects and
sometimes not is that a TranslationUnit object can be constructed from
state generated by the parser (Preprocessor; semantic analyzer, etc.), and thus
in these cases won't own the IdentifierTable or Selectors, etc. During
deserialization, there is no Preprocessor, so somebody needs to own these
objects in order for them to be properly reclaimed.

Added initial support into the flow-sensitive dataflow solver to visit the Block-level expression
...
in a block's terminator. This expression is visited within a block, but it is accessed by the
terminator. This is important to observe because for live-variables analysis the block-level
expression is live between the terminator and where the expression occurs in the block. So far
this hasn't been an issue to not observe this because the block-level expression used in the
terminator is always the last one in the block, and we have never queried the liveness information
about this point (but before the terminator).

Do an initial hack at replacing one of the incredibly inefficient

While this code is functional, it isn't very pretty, I have much

Major refactoring/cleanup of GRExprEngine, ExplodedGraph, and BugReporter.
...
Bugs are now reported using a combination of "BugType" (previously
BugDescription) and Bug "BugReport" objects, which are fed to BugReporter (which
generates PathDiagnostics). This provides a far more modular way of registering
bug types and plugging in diagnostics.
GRExprEngine now owns its copy of GRCoreEngine, and is not owned by the
ExplodedGraph.
ExplodedGraph is no longer templated on the "checker", but instead on the state
contained in the nodes.

Change ObjCInterfaceDecl to inherit from NamedDecl (not TypeDecl). While ObjCInterfaceDecl is arguably a TypeDecl, it isn't a ScopedDecl. Since TypeDecl's are scoped, it makes sense to simply treat them as NamedDecl's. I could have fiddled a bit more with the hierarchy (in terms of creating a non-scoped TypeDecl), however this probably isn't worth the effort.
...
I also finished unifying access to scope decl change by converting Sema::getObjCInterfaceDecl() to use Sema::LookupDecl(). This is much cleaner now:-)

Two changes to Sema::LookupDecl() interface.
...
(1) Remove IdLoc (it's never used).
(2) Add a bool to enable/disable lazy builtin creaation (defaults to true).
This enables us to use LookupDecl() in Sema::isTypeName(), which is also part of this commit.
To make this work, I changed isTypeName() to be a non-const member function. I'm not happy with this, however I fiddled with making LookupDecl() and friends const and it got ugly pretty quickly. We can certainly add it back if/when someone has time to fiddle with it. For now, I thought this simplification was more important than retaining the const-ness.

Fix several bugs in array -> pointer decomposition.
...
First, we got several CVR propagation cases wrong, which Eli pointed
out in PR2039.
Second, we didn't propagate address space qualifiers correctly, leading
to incorrect lowering of code in CodeGen/address-space.c.
Third, we didn't uniformly propagate the specifier in the array to the
pointer ("int[restrict 4]" -> "int *restrict").
This adds an ASTContext::getArrayDecayedType member that handles the
non-trivial logic for this seemingly simple operation.

Fix objc ivar lookup. Ivar lookup should occur between lookup

Two todo's left:
1) sema shouldn't turn a bare reference to an ivar into "self->ivar"
in the AST. This is a hack.
2) The new ScopedDecl::isDefinedOutsideFunctionOrMethod method does
not correctly handle typedefs and enum constants yet.

some cleanups on top of David's patch. There are still two
...
remaining open issues I've communicated to him:
1) self can be assigned to, and his patch didn't handle it correctly.
2) CollectObjCIvarTypes is N^2 (because each subclass reprocesses
all parent class ivars) and flattens classes. If A derives from B,
and both have an int, I'd expect to get { {i32}, i32}, not { i32, i32}.

Make a major restructuring of the clang tree: introduce a top-level
...
lib dir and move all the libraries into it. This follows the main
llvm tree, and allows the libraries to be built in parallel. The
top level now enforces that all the libs are built before Driver,
but we don't care what order the libs are built in. This speeds
up parallel builds, particularly incremental ones.
