6b8e91e7e3 Long double patch 8 of N: make it partially work in 
SSE mode (all but conversions <-> other FP types, I think):
>>Do not mark all-80-bit operations as "Requires[FPStack]"
(which really means "not SSE").
>>Refactor load-and-extend to facilitate this.
>>Update comments.
>>Handle long double in SSE when computing FP_REG_KILL.

2c35d56edd Long double patch 7 of N, unless I lost count:). 
Last x87 bits for full functionality (not
thoroughly tested, and long doubles do not work
in SSE modes at all - use -mcpu=i486 for now)

67d3119773 This resolves a regression of BasicAA which failed to find any memory information for overloaded intrinsics (PR1600). This resolves that issue, and improves the matching scheme to use a BitVector rather than a binary search.

e717210757 This fixes resizing issues with BitVectors. It ensures that the BitWord type and type size is always used, and ensures completely correct clearing of unused high bits, and setting of bits when resizing. It should resolve PR1563.

2c559ed3dc 1. Random tidiness cleanups 
2. Make domtree printing print dfin/dfout #'s
3. Fix the Transforms/LoopSimplify/2004-04-13-LoopSimplifyUpdateDomFrontier.ll failure from last night (in DominanceFrontier::splitBlock).

w.r.t. #3, my patches last night happened to expose the bug, but this 
has been broken since Owen's r35839 patch to LoopSimplify.  The code
was subsequently moved over from LoopSimplify into Dominators, carrying
the latent bug.  Fun stuff.
