This new version is much more aggressive about doing "full" reduction in
cases where it reduces register pressure, and also more aggressive about
rewriting induction variables to count down (or up) to zero when doing so
reduces register pressure.

It currently uses fairly simplistic algorithms for finding reuse
opportunities, but it introduces a new framework allows it to combine
multiple strategies at once to form hybrid solutions, instead of doing
all full-reduction or all base+index.

Fix a minor issue in x86 load / store folding table. movups does an unaligned load so it doesn't require 16-byte alignment.

necessary to keep two Decl's descriptor unique if their name match.

There is more work to do to create descriptors for DeclContext. 
As a temp. step use type's name in FwdDecl.

This means the AsmLexer no longer requires a SourceMgr
to do error handling.

So, casting a generic object pointer ('id' or 'Class') to the
block pointer is allowed. Fixes radar 7562285.

MachineModuleInfoMachO instead.  This eliminates two sources

children of a given cursor, regardless of what kind of cursor it
is. This is a generalization of clang_loadDeclaration and
clang_loadTranslationUnit that will also extent to statements,
expressions, etc.

As proof-of-concept, switched clang_loadDeclaration() from its own
visitor over to an instance of this traversal function internally.

When XDEBUG is enabled, check for SelectionDAG cycles at some key
