Slightly change TableGen's definition of a register subclass.
...
A subclass is allowed to have a larger spill size than the superclass, and the
spill alignment must be a multiple of the superclass alignment. This causes
the following new subclass relations:
=== Alpha ===
F4RC -> F8RC
=== PPC ===
F4RC -> F8RC
=== SPU ===
R8C -> R16C -> R32C/R32FP -> R64C/R64FP -> GPRC/VECREG
=== X86 ===
FR32 -> FR64 -> VR128
RFP32 -> RFP64 -> RFP80
These subclass relations are consistent with the behaviour of -join-cross-class-copies.

Extend ScalarEvolution's getBackedgeTakenCount to be able to
...
compute an upper-bound value for the trip count, in addition to
the actual trip count. Use this to allow getZeroExtendExpr and
getSignExtendExpr to fold casts in more cases.
This may eventually morph into a more general value-range
analysis capability; there are certainly plenty of places where
more complete value-range information would allow more folding.

Add a smarter heuristic to determine when to coalesce a virtual register with a physical one. More specifically, it avoid tying a virtual register in the loop with a physical register defined / used outside the loop. When it determines it's not profitable, it will use the physical register as the allocation preference instead.
...
This is *not* turned on by default. Testing indicates this is just as likely to pessimize code. The main issue seems to be allocation preference doesn't work effectively. That will change once I've taught register allocator "swapping".
