Argyrios Kyrtzidis e552941316 [libclang] Fix getting a cursor inside an angled #include directive.
Fixed by pointing the end location of the preprocessed entity for the #include
at the closing '>', instead of the start of '<'.

David Blaikie 6154ef97a3 Fix PR13784: instantiation of an abstract class in a conditional operator.
A couple of missing "RequireNonAbstractType" calls in conditional operator
handling. I looked for opportunities to tie this check in to all relevant
callers of PerformCopyInitialization (couldn't be all callers since this is
called for base subobject copying too, where it's acceptable to copy abstract
types) but the callers varied too much & in many cases had substantial code
or conditionals on the RequireNonAbstractType call, the
PerformCopyInitialization call, or the code between the two calls.

Jordan Rose 1e0e4001c8 [analyzer] For now, don't inline C++ standard library functions.
This is a (heavy-handed) solution to PR13724 -- until we know we can do
a good job inlining the STL, it's best to be consistent and not generate
more false positives than we did before. We can selectively whitelist
certain parts of the 'std' namespace that are known to be safe.

This is controlled by analyzer config option 'c++-stdlib-inlining', which
can be set to "true" or "false".

This commit also adds control for whether or not to inline any templated
functions (member or non-member), under the config option
'c++-template-inlining'. This option is currently on by default.

Dmitri Gribenko 7acbf00f96 Comment AST: TableGen'ize all command lists in CommentCommandTraits.cpp.
Now we have a list of all commands.  This is a good thing in itself, but it
also enables us to easily implement typo correction for command names.

With this change we have objects that contain information about each command,
so it makes sense to resolve command name just once during lexing (currently we
store command names as strings and do a linear search every time some property
value is needed).  Thus comment token and AST nodes were changed to contain a
command ID -- index into a tables of builtin and registered commands.  Unknown
commands are registered during parsing and thus are also uniformly assigned an
ID.  Using an ID instead of a StringRef is also a nice memory optimization
since ID is a small integer that fits into a common bitfield in Comment class.

This change implies that to get any information about a command (even a command
name) we need a CommandTraits object to resolve the command ID to CommandInfo*.
Currently a fresh temporary CommandTraits object is created whenever it is
needed since it does not have any state.  But with this change it has state --
new commands can be registered, so a CommandTraits object was added to
ASTContext.

Also, in libclang CXComment has to be expanded to include a CXTranslationUnit
so that all functions working on comment AST nodes can get a CommandTraits
object.  This breaks binary compatibility of CXComment APIs.

Now clang_FullComment_getAsXML(CXTranslationUnit TU, CXComment CXC) doesn't
need TU parameter anymore, so it was removed.  This is a source-incompatible
change for this C API.

DeLesley Hutchins 5ff1644e62 Thread-safety analysis: differentiate between two forms of analysis; a precise
analysis that may give false positives because it is confused by aliasing, and

Ted Kremenek 3d92699d3c Take another crack at stabilizing the emission order of analyzer
diagnostics without using FoldingSetNodeIDs.  This is done
by doing a complete recursive comparison of the PathDiagnostics.

Note that the previous method of comparing FoldingSetNodeIDs did
not end up relying on unstable things such as pointer addresses, so
I suspect this may still have some issues on various buildbots because
I'm not sure if the true source of non-determinism has been eliminated.
The tests pass for me, so the only way to know is to commit this change
and see what happens.

Jordan Rose 5481cfefa6 [analyzer] ObjCSelfInitChecker should always clean up in postCall checks.
ObjCSelfInitChecker stashes information in the GDM to persist it across
function calls; it is stored in pre-call checks and retrieved post-call.
The post-call check is supposed to clear out the stored state, but was
failing to do so in cases where the call did not have a symbolic return
value.

This was actually causing the inappropriate cache-out from r163361.
Per discussion with Anna, we should never actually cache out when
assuming the receiver of an Objective-C message is non-nil, because
we guarded that node generation by checking that the state has changed.
Therefore, the only states that could reach this exact ExplodedNode are
ones that should have merged /before/ making this assumption.

r163361 has been reverted and the test case removed, since it won't
actually test anything interesting now.

Jordan Rose 5860e329a4 [analyzer] Remove constraints on dead symbols as part of removeDeadBindings.
Previously, we'd just keep constraints around forever, which means we'd
never be able to merge paths that differed only in constraints on dead
symbols.

Because we now allow constraints on symbolic expressions, not just single
symbols, this requires changing SymExpr::symbol_iterator to include
intermediate symbol nodes in its traversal, not just the SymbolData leaf
nodes.
