Add new states for symbolic regions tracked by malloc checker. This enables us
to do malloc checking more accurately. See test case.

Based on Lei Zhang's patch and discussion.

This was super-easy, since we already had decent recovery by looking
for names in dependent base classes.

after the MDNode in memory.  This eliminates the operands
pointer and saves a new[] per node.

Note that the code in DIDerivedType::replaceAllUsesWith is wrong
and quite scary.  A MDNode should not be RAUW'd with something
else: this changes all uses of the mdnode, which may not be debug
info related!  Debug info should use something non-mdnode for
declarations.

this manifests as any real change though, we're still
not getting the right LLVM IR attributes out of codegen.

so can be a huge performance issue when tearing down modules and mdnodes
are not guaranteed to be unique anyway.  This speeds up:

To make this really useful, we'll need to introduce typo correction in
many more places (wherever we do name lookup), and implement
declaration-vs-expression heuristics that cope with typos
better. However, for now this will handle the simple cases where we
already get good "unknown type name" diagnostics.

The LookupVisibleDecls functions are intended to be used by code
completion as well as typo correction; that refactoring will happen
later.
