a separate DCE pass over MachineInstrs.

First loop test passed.  The data structure and search algorithm is still crude and in-flux.  But this milestone needed to be locked in.  Right now every loop is implemented in terms of a structure that will handle the most complicated {min, max} loop.  Though only *-loops are tested at the moment.  In a future iteration *-loops will likely be optimized a little more.  The only tests are for basic posix so far, but I have prototype code running for extended posix and ecma.  The prototype code lacks the complicating properties of the real <regex> requirements though.

to operate at an arbitrary position within a block, rather than just
appending to a block.

This eliminates an NDEBUG ABI sensitivity.

interface needs implementations to be consistent, so any code which
wants to support different semantics must use a different interface.
It's not currently worthwhile to add a new interface for this new
concept.

Document that AliasAnalysis doesn't support cross-function queries.

This has 2 (slight) advantages:
-Make explicit at getBody()'s callsite that we expect/handle only CompoundStmt and not CXXTryStmt.
-Better tracking of Decl::getBody()'s callsites.

Introduce Decl::hasBody() and FunctionDecl::hasBody() and use them instead of getBody() when we are just checking the existence of a body, to avoid de-serialization of the body from PCH.

Makes de-serialization of the function body even more "lazier".
