MultiTestRunner: Simplify, cleanup, and rename!
 - MultiTestRunner will eventually be renamed to 'lit', for LLVM integrated

 - "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.

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

Use an IdentifierTable for names used for Entities.

-Introduce the idx::Analyzer class used for getting indexing information, like finding
references of a declaration across translation units.

-Modify the index-test tool to use it.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77536 91177308-0d34-0410-b5e6-96231b3b80d8

Introduce TULocation and TULocationHandler classes.

TULocation is like ASTLocation but also contains the TranslationUnit* that
the ASTLocation originated from.

Modify the Indexer class so that it can return the TranslationUnit that internal
decls originated from.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77534 91177308-0d34-0410-b5e6-96231b3b80d8

Add Entity::getInternalDecl() to be used only on Entities that refer to internal
(in translation unit) declarations.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77533 91177308-0d34-0410-b5e6-96231b3b80d8

Constify ASTLocation::print.

Fix some comments.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77531 91177308-0d34-0410-b5e6-96231b3b80d8

Add getDeclReferenceMap() to the abstract interface of TranslationUnit class.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77530 91177308-0d34-0410-b5e6-96231b3b80d8

Remove the TranslationUnit usage from clang-wpa.cpp since it's not really
necessary.

Introduce a helper template for the Handler classes and use it instead
of the iterator of the Indexer class.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77528 91177308-0d34-0410-b5e6-96231b3b80d8

Add an assert.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77527 91177308-0d34-0410-b5e6-96231b3b80d8

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.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77526 91177308-0d34-0410-b5e6-96231b3b80d8

Rename EntityHandler::HandleEntity to Handle.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77525 91177308-0d34-0410-b5e6-96231b3b80d8

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

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77524 91177308-0d34-0410-b5e6-96231b3b80d8

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.
