<rdar://problem/13509689> Introduce -module-file-info option that provides information about a particular module file.

This option can be useful for end users who want to know why they
ended up with a ton of different variants of the "std" module in their
module cache. This problem should go away over time, as we reduce the
need for module variants, but it will never go away entirely.

Added two new narrowing matchers:
* hasMethod: aplies a matcher to a CXXRecordDecl's methods until a match is made
  or there are no more methods.
* hasCanonicalType: applies a matcher to a QualType's canonicalType.

Enhanced hasOverloadedOperatorName to work on CXXMethodDecl as well as
CXXOperatorCallExpr.

Updated tests and docs.

Instead of passing NULL on to sub-matcher, just return false. Updated tests and
regenerated docs.

Also document the rule that Doug implemented a few weeks ago
which drops ownership qualifiers on function result types.

This enables constructor inlining for types with non-trivial destructors.
The plan is to enable destructor inlining within the next month, but that
needs further verification.

These are two related changes (one in llvm, one in clang).
LLVM: 
- rename address_safety => sanitize_address (the enum value is the same, so we preserve binary compatibility with old bitcode)
- rename thread_safety => sanitize_thread
- rename no_uninitialized_checks -> sanitize_memory

CLANG: 
- add __attribute__((no_sanitize_address)) as a synonym for __attribute__((no_address_safety_analysis))
- add __attribute__((no_sanitize_thread))
- add __attribute__((no_sanitize_memory))

for S in address thread memory
If -fsanitize=S is present and __attribute__((no_sanitize_S)) is not
set llvm attribute sanitize_S

New type matchers:
* recordType
* elaboratedType

New narrowing matchers:
* hasQualifier
* namesType
* hasDeclContext

Added tests and updated LibASTMatchersReference.

TemplateSpecializationType doesn't quite have getDecl(). Need to go
through TemplateName to get a TemplateDecl.

Added test cases for the hasDeclaration() overload for
TemplateSpecializationType. Also introduced the type matcher
templateSpecializationType() used by the new hasDeclaration() test case.

Updated LibASTMatchersReference.

After changing the way several value inheritance hierarchies (TypeLoc,
CFGelement, ProgramPoint and SVal) handle casting, this documentation describes
how 3rd party code may need to be updated to compile with the new APIs.

As suggested by Sean Silva on cfe-dev.
