c56e67644f Add CodeGenFunction::EmitBranch. 
- Emits an unconditional branch, with extra logic to avoid generating
   spurious branches out of dummy blocks.

5b1964b5f9 short circuit && and || when possible. This substantially reduces 
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.

aaaa199ad1 Make codegen smart enough to not emit the dead side of an if whose 
condition is a constant.  This shrinks -O0 codegen by quite a bit
on some cases.

b5d21a4d03 don't preserve names on IR instructions. This matches llvm-gcc's behavior and 
speeds up the compiler by ~8% at -emit-llvm -O0.

f61801403d Fix even more bugs in debug info support: 
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.

affb37337f reimplement debug info generation in terms of DebugInfo.h instead of 
using MachineModuleInfo.  This runs at about the same speed as the old
code, but fixes a bunch of bugs and is simpler and shorter.

d79592448b Made the mechanism of defining preprocessor defs for maxint, ptrdiff_t, wchar 
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.

c475d4224b NeXT: Emit protocol objects lazily. 
- 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.

5adca5f02c Fix for PR2966: va_start/va_end use the *address* of the 
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.

607f67b16c Map compilation units using FileEntry pointers instead of 
FileIDs. This seems better conceptually and lets the SourceManager
handle details of mapping the location to a file ID.
 - In practice, fixes an assert because this code wasn't using
   getPhysicalLoc.

88e1b97f16 Simplify handling of struct/union/class tags. 
Instead of using two sets of Decl kinds (Struct/Union/Class and CXXStruct/CXXUnion/CXXClass), use one 'Record' and one 'CXXRecord' Decl kind and make tag kind a property of TagDecl.
Cleans up the code a bit and better reflects that Decl class structure.
