Convert the last uses of CastInst::createInferredCast to a normal cast
creation. These changes are still temporary but at least this pushes
knowledge of signedness out closer to where it can be determined properly
and allows signedness to be removed from VMCore.

Remove the last use of getUnsignedVersion and getSignedVersion from VMCore.
ConstantInt doesn't care about the sign of the type it represents. It only
cares about the bitwidth so there is no need to make the sign of the type
match the SExt or ZExt constant expression.

Fix problems in the CBE and InstructionCombining which use the isMaxValue

Added an automatic cast to "std::ostream*" etc. from OStream. We then can

Avoid creating invalid sub/add instructions on the prolog/epilog

Fix a long-standing spiller bug:
If a spillslot value is available in a register, and there is a noop copy that
targets that register, the spiller correctly decide not to invalidate the
spillslot register.

However, even though the noop copy does not clobbers the value. It does start a
new intersecting live range. That means the spillslot register is available for
use but should not be reused for a two-address instruction modref operand which
would clobber the new live range.

When we remove the noop copy, update the available information by clearing the
canClobber bit.
