X86: Shrink certain forms of movsx.
...
In particular:
movsbw %al, %ax --> cbtw
movswl %ax, %eax --> cwtl
movslq %eax, %rax --> cltq
According to Intel's manual those have the same performance characteristics but
come with a smaller encoding.

As Dan pointed out, movzbl, movsbl, and friends are nicer than their alias
...
(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.

now that generic vector types aren't selected onto MMX registers, these

tests don't need -disable-mmx.
