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.

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.

'%al,' it would report 'al,' as the token.  Now it

cast needs to adjust for a vtable pointer when going from base to
derived type (when the base doesn't have a vtable but the
derived type does).

The 'R' suffix means the to-integer operations use the rounding mode specified

spot. If folding succeeds, emit the folded expression instead.

This fixes PR6255.

we can get in here if FastISel gives up in a block.
(Actually the two copies of this need to be unified.  Later.)
