be2d8c6096 Basic plumbing for generating a precompiled preamble for an 
ASTUnit/CXTranslationUnit. We can't actually use this preamble yet,
however.

af82e3510b Introduce a new lexer function to compute the "preamble" of a file, 
which is the part of the file that contains all of the initial
comments, includes, and preprocessor directives that occur before any
of the actual code. Added a new -print-preamble cc1 action that is
only used for testing.

dde5790562 Hide FunctionTemplateDecl's specializations folding set as implementation detail and introduce 
FunctionTemplateDecl::findSpecialization.

Redeclarations of specializations will not cause the previous decl to be removed from the set,
the set will keep the canonical decl. findSpecialization will return the most recent redeclaration.

aa21cc401b Introduce a new libclang API, clang_reparseTranslationUnit(), which 
reparses an already-parsed translation unit. At the moment it's just a
convenience function, but we hope to use it for performance
optimizations.

e38764c66c Driver: Change the driver to take the path to the main executable, instead of 
taking it in pieces.
 - Fixes a problem where the Clang executable path was not initialized properly
   on Win32, because sys::Path::getBasename() doesn't do what I always think it
   does. Imagine that, a sys::Path interface that is confusing!

826e6b4023 Improved false positive rate for the idempotent operations checker and moved it into the default path-sensitive analysis options. 
- Added checks for static local variables, self assigned parameters, and truncating/extending self assignments
- Removed command line option (now default with --analyze)
- Updated test cases to pass with idempotent operation warnings

85b2a6a430 Add a callback interface that allows interested parties to get notified whenever PCHReader deserializes a type or decl (and possibly other things in the future). Have PCHWriter implement these callbacks as noops and register to receive them if we're chaining PCHs. This will allow PCHWriter to track the IDs of these things, which it needs to write the dependent files. WIP

f2753b3b4e Downgrade the "when type is in parentheses, array cannot have dynamic 
size" error for code like 

  new (int [size])

to a warning, add a Fix-It to remove the parentheses, and make this
diagnostic work properly when it occurs in a template
instantiation. <rdar://problem/8018245>.

36745fda34 Modify the pragma handlers to accept and use StringRefs instead of IdentifierInfos. 
When loading the PCH, IdentifierInfos that are associated with pragmas cause declarations that use these identifiers to be deserialized (e.g. the "clang" pragma causes the "clang" namespace to be loaded).
We can avoid this if we just use StringRefs for the pragmas.

As a bonus, since we don't have to create and pass IdentifierInfos, the pragma interfaces get a bit more simplified.
