to MachineInstr, and start using them throughout the 
codebase.

tMOVCCi pattern only valid for low registers, as the Thumb1 mov immediate to
register instruction only works with low registers. Allowing high registers
for the instruction resulted in the assembler choosing the wide (32-bit)
encoding for the mov, but LLVM though the instruction was only 16 bits wide,
so offset calculations for constant pools became incorrect, leading to
out of range constant pool entries.

Previously spill registers, whose def indexes are not defined, would sometimes be improperly marked as coalescable with conflicting registers. The new findCoalesces routine conservatively assumes that any register with at least one undefined def is not coalescable with any register it interferes with.

Initial skeleton and SCEVUnknown lowering implemented,
the rest should come relatively quickly.  Move testcase

Move pass to right before SimplifyLibCalls - which is
moved down a bit so we can take advantage of a few opts.

direct MCExpr equivalents. Don't use MCExpr::Shr because it isn't
consistent between targets.

Document that MCExpr::Div, Mod, and the comparison operators are all
signed operators.

Document that the comparison operators' results are target-dependent.

Document that the behavior of shr is target-dependent.
