ModuleBuilder now performs llvmgen in HandleTranslationUnit.

This patch follows from the discussion on the following thread on cfe-commits:

Fix by Jordan Breeding: when scanning for prior runs, scan-build should ignore files that are not directories.

Fix --html-diags in driver by delaying the construction of an HTMLDiagnosticClient until after we have created the Preprocessor object.

Fixes <rdar://problem/6093889> Nested enum redefinition crashes sema.

Unify logic in return-of-stack-check (Sema) for casts and implicit casts.

Cleanup some processing with DeclStmt, and gradually start using the internal BumpPtrAllocator to allocator more of CFG's data structures.

 - Change hardcoded assembly instructions to a use of 'opt' (still
   waiting for someone to yell at me for this).

 - Add some cases to cover behavior fixed by previous commit.

llvm-svn: 54413

While this is a safe rewriter fix, there is still a need for some discussion (see report for more info).

llvm-svn: 54412

When serializing DeclStmt, encode a bit indicating whether or not the DeclStmt owns the Decl.  This is an interim solution.

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.

 - 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.

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.

  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.

llvm-svn: 54373

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.

Finish fixing <rdar://problem/5929344> clang ObjC rewriter: "extern int __CFConstantStringClassReference[];" should be extern "C"

llvm-svn: 54365

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.

 - Use -verify and added expected warnings for EXTWARN change.

llvm-svn: 54342

llvm-svn: 54340

 - ActOnDeclarator now takes an additional parameter which is the
   AsmLabel if used. Its unfortunate that this bubbles up this high,
   but we cannot just lump it in as an attribute without mistakenly
   *accepting* it as an attribute.
 - The actual asm-label itself is, however, encoded as an AsmLabelAttr
   on the FunctionDecl.
 - Slightly improved parser error recovery on malformed asm-labels.
 - CodeGen support still missing...
