Enhance CodePlacementOpt's unconditional intra-loop branch elimination logic
...
to be more general and understand more varieties of loops.
Teach CodePlacementOpt to reorganize the basic blocks of a loop so that
they are contiguous. This also includes a fair amount of logic for preserving
fall-through edges while doing so. This fixes a BranchFolding-ism where blocks
which can't be made to use a fall-through edge and don't conveniently fit
anywhere nearby get tossed out to the end of the function.

Merge the "types" and "declarations" blocks in the precompiled header
...
format, so that we don't end up with multiple declaration and types
blocks. Also, fix a few obscure bugs with PCH loading and generation:
- If the DeclIDs DenseMap reallocates while we are writing a
declaration (due to recursively writing other declarations), we
could end up writing a bad ID to ExternalDefinitions.
- When loading an ArrayLoc (part of DeclaratorInfo), we need to set
the size expression to NULL if no size expression was provided.
PCH -> AST rewriting is still partly broken, unfortunately.

only supporting a single stat cache. The immediate benefit of this

be useful with multiple levels of PCH files.
