Determine which loop exit blocks need a 'pre-exit' block inserted.
Recognize when this would be impossible.

bitcode file, so that two bitcode files where the same metadata kind
name happens to have been assigned a different ID can still be
linked together.

Eliminate the restriction that metadata kind IDs can't be 0.

Change MD_dbg from 1 to 0, because we can now, and because it's
less mysterious that way.

Move more functionality from Pass.cpp to PassRegistry.cpp.  This global will go away eventually, but for now we still need it around.

better in the llvm world.  Among other things, this changes:

1. The guts of libedis are now moved into lib/MC/MCDisassembler
2. llvm-mc now depends on lib/MC/MCDisassembler, not tools/edis,
   so edis and mc don't have to be built in series.
3. lib/MC/MCDisassembler no longer depends on the C api, the C
   API depends on it.
4. Various code cleanup changes. 

There is still a lot to be done to make edis fit with the llvm
design, but this is an incremental step in the right direction.

one loop is involved in the increment of an addrec for another

Pull out r108755.  After offline discussion with Chris, we're going to go a different direction with this.
