From 29e874dd2e7e40a3276af38bc2cfafd3af8230f6 Mon Sep 17 00:00:00 2001

Subject: Two part patch:

First: refactor out the emission of entries into the .debug_loc section
into its own routine.

Second: add a new class ByteStreamer that can be used to either emit
using an AsmPrinter or hash using DIEHash the series of bytes that
would be emitted. Use this in all of the location emission routines
for the .debug_loc section.

No functional change intended outside of a few additional comments
in verbose assembly.
