Implement RegionStoreManager::RemoveDeadBindings(). This prunes several false warning caused by removal of symbolic constraints. Currently we just mark all symbols live. Further optimization for dead binding removal needed.

Fixes ppc32 bootstrap.

The previous patches didn't match correctly. Also, we need to make sure that
the conditional is the same before doing the transformation.

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.

code, but fixes a bunch of bugs and is simpler and shorter.

Print integer value instead of raw pointer. This is a hack to be fixed by migrating the output in analyzer to llvm::raw_ostream.

information.  This logically replaces the "Desc" classes in
MachineModuleInfo.  Nice features of these classes are that they:

1. Are much more efficient than MMI because they don't create a 
   temporary parallel data structure for debug info that has to be
   'serialized' and 'deserialized' into/out of the module.
2. These provide a much cleaner abstraction for debug info than 
   MMI, which will make it easier to change the implementation in 
   the future (to be MDNode-based).
3. These are much easier to use than the MMI interfaces, requiring
   a lot less code in the front-ends.
4. These can be used to both create (for frontends) and read (for
   codegen) debug information.  DebugInfoBuilder can only be used
   to create the nodes.

So far, this is implemented just enough to support the debug info
generation needs of clang.  This can and should be extended to 
support the full set of debug info constructs, and we should switch
llvm-gcc and llc over to using this in the near future.

This code also has a ton of FIXMEs in it, because the way we 
currently represent debug info in LLVM IR is basically insane in a
variety of details.  This sort of issue should be fixed when we
eventually reimplement debug info on top of MDNodes.

Introduce ScopedDecl::getLexicalDeclContext() which is different from ScopedDecl::getDeclContext() when there are nested-names.
e.g.:
  namespace A {
    void f(); // SemanticDC (getDeclContext) == LexicalDC (getLexicalDeclContext) == 'namespace A'
  }
  void A::f(); // SemanticDC == namespace 'A'
               // LexicalDC == global namespace

of the select match, not the select instruction itself.

llvm-svn: 58947

original code was matching like this:

	if (match(A, m_Not(m_Value(B))))

B was already matched as a 'select' instruction. However, this isn't matching
what we think it's matching. It would match B as a 'Value', so basically
anything would match to it. In this case, a Constant matched. B was replaced
with a constant representation. And then the wrong value would be used in the
SelectInst::Create statement, causing a crash.

After thinking on this for a moment, and after Nick L. told me how the pattern
matching stuff was supposed to work, the solution was to match NOT an m_Value,
but an m_Select.

When a tag has nested-name ('struct foo::bar'), use not 'CurContext' but the context of the nested-name ('foo::').

-Also use the ActOnTagStruct code path.
