- This ended up being hard to factor, sorry for the large diff.

 - Some post-commit cleanup to come.

Add FrontendActions, which provides a FrontendAction interface to all the existing AST consumer based clang-cc actions.

 - Not tested, but -verify with multiple inputs should work now.

llvm-svn: 88750

 - This reimplements -verify as just another DiagnosticClient, which buffers the diagnostics and checks them when the source file is complete. There are some hacks to make this work, but they are all internal, and this exposes a better external interface.

 - This also tweaks a few things:
   o Errors are now just regular diagnostics.
   o Frontend diagnostics are now caught (for example, errors in command line arguments), although there isn't yet a way to specify that they are expected. That would be nice though.

 - Not yet used.

 - The design philosophy is in the CompilerInstance doxyment, if you don't agree
   with it now would be a good time to speak up.

Add clang-cc option "-analyzer-experimental-checks" to enable experimental path-sensitive checks.  The idea is to separate "barely working" or "skunkworks" checks from ones that should always run.  Later we need more fine-grain checker control.

This resolves the layering violation where CodeGen depended on Frontend.

"This adds definitions for types of 8-bit multiples
from 8 to 64 to stdint.h and rationalizes the selection of types 
for the exact-width definitions in InitPreprocessor.cpp."

This prevents them from getting out of synch, patch by Ken Dyck!

not doing this has little to no utility.

Allow Preprocessor to take ownership of the HeaderSearch object. I think it should probably always own the header search object, but I'm not sure...
