 - Only focusing on llvm_gcc_c for now, eventually this needs to be
   refactored so it can be shared via all the gcc-like tools.

Register scavenger should process early clobber defs first. A dead early clobber def should not interfere with a normal def which happens one slot later.

and FP_ROUND.  Not sure what these were doing
here - probably they were sometimes (wrongly)
created with integer operands somewhere that
has since been fixed.

SCALAR_TO_VECTOR.  I didn't add the testcase, because
once llc gets past scalar-to-vector it hits a SPU target
lowering bug and explodes.

Use it to safely handle less-than-or-equals-to exit conditions in loops. These
also occur when the loop exit branch is exit on true because SCEV inverses the
icmp predicate.

Use it again to handle non-zero strides, but only with an unsigned comparison
in the exit condition.
