The implementations of these methods can Use Decl::getASTContext() to get the ASTContext.

This commit touches a lot of files since call sites for these methods are everywhere.
I used pre-tokenized "carbon.h" and "cocoa.h" headers to do some timings, and there was no real time difference between before the commit and after it.

___Block_byref_id_object_dispose and ___Block_byref_id_object_copy
functions so that we can simply reuse instead of creating a new one.
Additionally, add an assert to ensure no one yet tries to align a
__block variable beyond the alignment of a pointer as the codegen is
incomplete.

Targets like PIC16 generate Static decls for automatic variables, emit the appropriate debug descriptor as well in that case.

Since we miscompile many cases when declaring a variable with a reference type, make them unsupported for now.

variables.  For this to work, the backend needs to handle more complex
forms for locations.

A typical utterance would be:

        %forwarding = getelementptr %0* %use_by_ref, i32 0, i32 1               ; <i8**> [#uses=1]
        %0 = load i8** %forwarding              ; <i8*> [#uses=1]
        %1 = bitcast i8* %0 to %0*              ; <%0*> [#uses=1]
        %x = getelementptr %0* %1, i32 0, i32 4         ; <i32*> [#uses=1]
        %2 = bitcast i32* %x to { }*            ; <{ }*> [#uses=1]
        call void @llvm.dbg.declare({ }* %2, { }* bitcast (%llvm.dbg.variable.type* @llvm.dbg.variable to { }*))

Presently when selection finds something it doesn't understand, it
just avoids generating any information, which is safe, just
incomplete.  Radar 6867696

to allow us to support generation of deferred ctors/dtors.
It looks like codegen isn't emitting a call to the dtor in 
member-functions.cpp:test2, but when it does, its body should
get emitted.

When calling the cleanup function specified by __attribute__((cleanup)), make sure to bitcast the argument so it has the same type as the first argument of the cleanup function. Fixes <rdar://problem/6827047>.

 - Exposed quite a few Sema issues and a CodeGen crash.

 - See FIXMEs in test case, and in SemaDecl.cpp (PR3983).

I'm skeptical that __private_extern__ should actually be a storage
class value. I think that __private_extern__ basically amounts to
  extern A __attribute__((visibility("hidden")))
and would be better off handled (a) as that, or (b) with an extra bit
in the VarDecl.
