a bunch of code from all the targets, and eliminates nondeterministic
ordering of directives being emitted in the output.

6bbcba18db Move the special cases for constants out of getUnknown and into
createSCEV. Also, recognize UndefValue in createSCEV.

Change getIntegerSCEV's comment to avoid mentioning FP types,
and re-implement it in terms of getConstant instead of getUnknown.

f49810c7e6 Initial Thumb2 support. Majority of the work is done by David Goodwin. There are
also some contribution from Jim Grosbach, Bob Wilson, and Evan Cheng.

I've done my best to consolidate the patches with those that were done by
Viktor Kutuzov and Anton Korzh from Access Softek, Inc. Let me know if missed
anything. I've completely reorganized the thumb2 td file, made more extensive
uses of multiclass, etc.

Test cases will be contributed later after I re-organize what's in svn first.

predicate does not check if Thumb mode is enabled, and when in ARM mode
there are still some checks for constant-pool use that need to run.

doesn't, etc.

f9f1da17f8 - Update register allocation hint after coalescing. This is done by the target since the hint is target dependent. This is important for ARM register pair hints.
- Register allocator should resolve the second part of the hint (register number) before passing it to the target since it knows virtual register to physical register mapping.
- More fixes to get ARM load / store double word working.
