Introduce a single AST node SizeOfAlignOfExpr for all sizeof and alignof expressions, both of values and types.

 - Emits an unconditional branch, with extra logic to avoid generating
   spurious branches out of dummy blocks.

the size of the -O0 output on some cases.  For example, on expr.c from
176.gcc, it shrinks the .ll file from 43164 to 42835 lines, and removed
references to two external symbols.

condition is a constant.  This shrinks -O0 codegen by quite a bit
on some cases.

"dummy" blocks (blocks just used to make sure we have a place to dump
code to).

speeds up the compiler by ~8% at -emit-llvm -O0.

1. emit proper debug info for forward decls of structs.
2. emit DW_TAG_member nodes around members of a field like llvm-gcc does.

This slows down debug info generation, but is required for correctness.

using MachineModuleInfo.  This runs at about the same speed as the old
code, but fixes a bunch of bugs and is simpler and shorter.

etc more generic. For some targets, long may not be equal to pointer size. For
example: PIC16 has int as i16, ptr as i16 but long as i32.

Also fixed a few build warnings in assert() functions in CFRefCount.cpp,
CGDecl.cpp, SemaDeclCXX.cpp and ParseDeclCXX.cpp.

 - That is, the metadata for a protocol is only emitted if that
   protocol is actually used in the translation unit. This is
   important because Objective-C headers frequently contain a large
   number of protocol definitions, only a few of which will be used in
   any given file.

va_list, not the value.  Patch fixes an assert on 
x86-64 and a wrong-code bug on x86.  I'm not completely sure, 
but I think it's a regression from r58306.

Does anyone run regression tests regularly on x86-64? The crash should 
have been picked up there.

FileIDs. This seems better conceptually and lets the SourceManager
handle details of mapping the location to a file ID.

   getPhysicalLoc.
