Convert the internal PassRegistrar class into a new, external PassRegistry class.  No intended functionality change at this point.

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
loop. This fixes rdar://8168938.

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

This is a work in progress. So far we have some basic loop analysis to help
determine where it is useful to split a live range around a loop.

The actual loop splitting code from Splitter.cpp is also going to move in here.

Also fix access of private member type by << operator.

- Fix a typo for PIC check during jmp table lowering
- Also fix the "first jump table basic block is not
considered only reachable by fall through" problem, use this
ad-hoc solution until I come up with something better.

Speculatively revert r108813, in an attempt to get the self-host buildbots working again.  I don't see why this patch
would cause them to fail the way they are, but none of the other intervening patches seem likely either.
