Make canonicalization of overloaded function declarations match the
Itanium C++ ABI's name mangling, since both are related to the notion

MultiTestRunner: Simplify, cleanup, and rename!
 - MultiTestRunner will eventually be renamed to 'lit', for LLVM integrated
   tester/testing. This has the pros of being pronouncable and short.

 - "Project" level configuration lives in 'lit.cfg', which is also what lit uses
   to find the root testing directory in some cases. This can be overridden for
   use in project files which want to precisely specify where things are.

 - TestRunner.py is not longer able to be invoked directly.

 - Moved some code to Util.py.

 - Introduced a configuration object.

 - Cleaned up --help, removed a few not-very-useful options.

 - Tried not to break anything that works. :)

Canonicalization and profiling for overloaded function declarations,

Fix use-after-release bug introduced in r77585 where the PathDiagnosticClient
created by AnalysisConsumer would be released by an instance of AnalysisManager
and then reused by later instances of AnalysisManager. Ownership of the
PathDiagnosticClient now belongs (for now) in AnalysisConsumer.

We also need this layering (for now) because the HTMLDiagnostiClient requires
that the entire translation unit be processed before emitting diagnostics. This
is done in its destructor (which should also be fixed, but that is another
issue).

Accept Handler objects in parameters as references.

Reinforces that they shouldn't be null and it's a bit more natural when
they are passed as stack objects.

-Make IndexProvider an abstract interface for getting indexing information.
-Introduce Indexer as an IndexProvider implementation.

Make tag declarations redeclarable. This change has three purposes:

  1) Allow the Index library (and any other interested client) to walk
  the set of declarations for a given tag (enum, union, class,
  whatever). At the moment, this information is not readily available.

  2) Reduce our dependence on TagDecl::TypeForDecl being mapped down
  to a TagType (for which getDecl() will return the tag definition, if
  one exists). This property won't exist for class template partial
  specializations.

  3) Make the canonical declaration of a TagDecl actually canonical,
  e.g., so that it does not change when the tag is defined.

Eliminate an unused-variable warning

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77518 91177308-0d34-0410-b5e6-96231b3b80d8

Update for LLVM API change.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77514 91177308-0d34-0410-b5e6-96231b3b80d8

Change uses of:
  Type::getAsReferenceType() -> Type::getAs<ReferenceType>()
  Type::getAsRecordType() -> Type::getAs<RecordType>()
  Type::getAsPointerType() -> Type::getAs<PointerType>()
  Type::getAsBlockPointerType() -> Type::getAs<BlockPointerType>()
  Type::getAsLValueReferenceType() -> Type::getAs<LValueReferenceType>()
  Type::getAsRValueReferenceType() -> Type::getAs<RValueReferenceType>()
  Type::getAsMemberPointerType() -> Type::getAs<MemberPointerType>()
  Type::getAsReferenceType() -> Type::getAs<ReferenceType>()
  Type::getAsTagType() -> Type::getAs<TagType>()

And remove Type::getAsReferenceType(), etc.

This change is similar to one I made a couple weeks ago, but that was partly
reverted pending some additional design discussion. With Doug's pending smart
pointer changes for Types, it seemed natural to take this approach.

Remove 'StoreManager::OldCastRegion()', TypedViewRegion (which only
OldCastRegion used), and the associated command line option
'-analyzer-store=old-basic-cast'.

Some refactoring of member access for
performace sake. Also added a test case.

Check accessibility when converting object to the base
class.

No longer need to keep base class offsets in the offset
table as it has its own place now.

Patch to provide cast of objects in member access
excpression, if needed, and remove some ir-gen code
now unnencessary.

[llvm up]

A template name can refer to a set of overloaded function
templates. Model this in TemplateName, which can now refer to an
OverloadedFunctionDecl that contains function templates. This removes
an unspeakable hack in Sema::isTemplateName.

Add an XFAILed test case that currently crashes for RegionStore. This case will
be moved to misc-ps.m when it passes.

Remove some uses of TypedViewRegion, and use getBaseRegion() in a context where
we don't care about ElementRegions layered on top of a base region.
