Daniel Dunbar e8bdce441b Fix EmitNullInitializationToLValue for bitfield lvalues.

Chris Lattner 7bdaecb7f4 Zap sitofp/fptoui pairs. In all cases when the sign difference 
matters, the result is undefined anyway.

Daniel Dunbar ead7c91240 Fix bitfield accesses which straddle the boundary of the underlying 
type.

 - This generates somewhat less optimal code than before but this is
   not hard to rectify once stable (at the cost of slightly more
   complex code).

 - This currently always uses little-endian ordering of the bitfield. 

 - This breaks the CodeGen/bitfield.c test because it was grepping for
   hard-coded assembly instructions. Will fix once a better test case
   is constructed (hard to do without execution).

 - This fixes SingleSource/UnitTests/2006-01-23-InitializedBitField.c
   and Regression/C/PR1386.c from the test suite.

tracking down that this was breaking llvm-gcc bootstrap on Linux.

Daniel Dunbar bfb1cd7454 Fix CodeGen of pointer arithmetic in compound assignment statements. 
- Changed EmitSub to work on all cases (arithmetic, ptr - int, ptr -
   ptr) so that implementation matches that of other operators.

 - Modify EmitCompoundAssign to compute and perform the appropriate
   casts of left, right, and result types for the assorted pointer
   arithmetic cases.

 - Fix EmitSub (ptr - int) case to negate the rhs *after*
   extension. This is critical when the rhs is unsigned (and needs
   extension).

 - This fixes cfrac.

Daniel Dunbar ffc29be83f Implement GNU asm-label extension support in CodeGen. This fixes 
scimark2 on Darwin.

 - Added Sema support for asm-label on variables, which I forgot before.

 - Update CodeGen to use GlobalDeclMap to determine if static Decls
   require emission (instead of LLVM module name lookup). Important
   since the Decl name and the LLVM module name can differ.

Dan Gohman ced4857365 Use strcpy instead of sprintf here. This avoids a GCC 4.3 format-string 
warning. There wasn't actually a problem here, because the contents of
the string are known.

Daniel Dunbar 829e988899 Change CodeGen of global decls to key off of the name (instead of 
having multiple bindings from all the possible decls which
  conceptually map to the same global).

 - This eliminates CodeGen depending on the LLVM module for name
   lookup.

 - This also eliminates the need for ReplaceMapValuesWith (hurrah).

 - This handles lookups for FunctionDecls correctly in the presence of
   aliases, this was previously broken.

 - WIP: Can still clean up & unify variable and function emission.

Ted Kremenek 4f8792b616 Added decl_iterator to DeclStmt to provide an abstract interface to iterate over the ScopedDecls of a DeclStmt. 
Updated a few clients of DeclStmt::getNextDeclarator() to use decl_iterator instead.  Will update other clients after additional testing.

Ted Kremenek 2c674f6dbb Refactored driver logic for CodeGen into LLVMCodeGenWriter. This ASTConsumer layers on top of LLVMCodeGen (another existing ASTConsumer) to emit bitcode files to disk. This layering takes this logic out of clang.cpp and puts it directly into the ASTConsumer interface. The benefit is that now --emit-llvm works with both serialized ASTs and regular source files.
