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
to new directory.

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

At the moment the inlinehint attribute is ignored by the Inliner unless you
pass a -respect-inlinehint option.  This will soon be the default.

The inlinehint attribute is set if the inline keyword is explicitly specified
on any declaration.

reinterpret_cast and I aren't getting along today.

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.
