a test.

Factor out a LangStandard class and coalesce the information about the standards into LangStandards.def
 - I'd appreciate another pair of eyeballs to double check this.

Add initial cut at CompilerInvocation::toArgs, which "serializes" the CompilerInvocation into a list of arguments which can be passed to clang-cc (eventually, clang -cc1).
 - Unfortunately, this is currently a tedious and manual translation. Eventually it would be nice to automatically generate this code.

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

 - 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.

Introduce the ResolveLocationInAST function which takes an ASTContext and a SourceLocation and it resolves it into a <Decl*, Stmt*> pair.

Decl* is the declaration associated with this source location and Stmt* is the statement/expression that the location points to.
If the location does not point to a statement node, Stmt* is null.

ResolveLocationInAST (along with converting a file:line:column triplet to a SourceLocation) will be useful for an IDE client and for clang's test suite.
