Change Sema::ActOnCallExpr to construct the CallExpr early and put it into
and OwningPtr instead of constructing only after all of sema is done.  This
has a couple of effects:
1. it fixes memory leaks from all the error cases in sema
2. it simplifies the code significantly.

The cost of this is that the error case now new's and delete's an expr where
it did not before, but we don't care about the perf of the error case.

Converted Loc back to being of type ProgramEdge. Ultimately I believe we want
the ability to refer to the vertex set for all the vertices associated with an
edge. This will allow some nice queries over the graph, and (hopefully) will
reduce the memory footprint of SimulVertex.

Changed "Location" from "ProgramEdge" to "ProgramEdge&" (slightly more svelt
memory representation).

This patch implements some of the more obscure type-checking involving
'id' quallified with protocols and static types which have categories and
inheritance which implement these protocols.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45294 91177308-0d34-0410-b5e6-96231b3b80d8

Updated Xcode project to be in sync with recent changes in file locations
introduced in r45292 (http://llvm.org/viewvc/llvm-project?rev=45292&view=rev)

Directory restructing of Analysis files.

Created include/clang/Analysis/Analyses directory.

Moved ExprDeclBitVector.h into Analysis/Support.

Updated all clients who use these headers to reflect the new paths.

Fixed successor order for CFG basic blocks when handling: x && y.  The bug
is best explained by illustration:

[ B2 ]
     1: x
     T: [B2.1] && ...
   Predecessors (1): B4
   Successors (2): B3 B1

Block "B3" should be the block where we evaluate "y" when "x" evaluates to
true. Previously we had the successor list reversed. Now this behavior matches
with how we handle other conditional branches.

Thanks to Nuno Lopes for reporting this problem.

Split serialization ASTConsumers into two consumers: SingleFileSerializer and
BuildSerializer. The former serializes a single translation unit to a
corresponding .ast file. The second serializes ASTs to a common emission
direction.  The latter is not fully implemented yet.

Added methods createMainFileID() and createMainFileIDForMemBuffer() to
SourceManager to allow SourceManager to directly intern the MainFileID
when it is created.  Removed setMainFileID().

Interned MainFileID within SourceManager. Since SourceManager is referenced by
both Preprocessor and ASTContext, we no longer need to explicitly pass
MainFileID around in function calls that also pass either Preprocessor or
ASTContext. This resulted in some nice cleanups in the ASTConsumers and the
driver.

Added storage of the FileID of the the main source file of a translation unit
in SourceManager.

Various tweaks to the get/lookup instance/class method API's.

Removed "SourceFile" from TranslationUnit. This same information will (soon)
be available by querying the SourceManager within the ASTContext referenced by
the TranslationUnit.

Cleaned up "-o" option to print "-o=<path>" instead of "-o=<string>" when
doing clang --help.

Added "-o" option to driver.  ASTConsumers will need to be gradually
rewired to utilize this option.

Renamed option --serialize-ast --serialize.

Add support for #pragma mark, which shouldn't warn about bogus tokens.

Removed storing inode and device number in TranslationUnit.

Added "SourceFile" string to TranslationUnit to record corresponding
source file.

Updated serialization of TranslationUnits and logic in the driver to
correctly pass the source file information to the serializer.
