(movzx/movsx) because they give more information. Revert that part of the patch.

Have the X86 back-end emit the alias instead of what's being aliased. In most
cases, it's much nicer and more informative reading the alias.

Disable 91381 for now. It's miscompiling ARMISelDAG2DAG.cpp.

Use sbb x, x to materialize carry bit in a GPR. The result is all one's or all zero's.
