This correctly handles partial redefines and undef uses.

definitions of the virtual register.

This happens when spilling the registers produced by REG_SEQUENCE:

%reg1047:5<def>, %reg1047:6<def>, %reg1047:7<def> = VLD3d8 %reg1033, 0, pred:14, pred:%reg0

The rewriter would spill the register multiple times, dead store elimination
tried to keep up, but ended up cutting the branch it was sitting on.

register is marked live after register allocation.

Add a createObjectStreamer() factory method so that the correct object
file streamer can be instantiated for a given target triple.

Factor its implementation to ease the addition of these custom edges to
traverse. With this patch we get initializer expressions, block bodies, type
source info, and function argument, result, and exception types. There are
probably still some more missed edges.

While we're here, clean up and flesh out a bunch of comments.

Patch by Zhanyong Wan; I've done a cursory review, but further review
appreciated. This is fast becoming one of the most important public APIs to the
AST.
