start straightening out libedis's dependencies and make it fit
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.

Simplify this code; LoopInfo::getCanonicalInductionVariable will only
find integer induction variables.

Change an argument from an Instruction* to a Value*, which is all
that is needed here.

initial checkin for unittest to exercise Support/Casting.h

this is still minimal on purpose, but I plan to migrate the ugly
hack under #ifdef DEBUG_CAST_OPERATORS into this file

Using BIC for immediates needs an extra bump for its complexity to get

The same problem was being tracked in PR7652.

Beginning SplitKit - utility classes for live range splitting.

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.

Oops - I tables render poorly in Chrome without this explicit height specification.

Use run-length encoding to represent identical adjacent cells in the pressure
and interval table. Reduces output HTML file sizes by ~80% in my test cases.

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

Added support for turning HTML indentation on and off (indentation off by default).
