[X86] Regenerated + extended widened vector conversion tests
...
- Ensure we test X86 + X64
- sitopfp / uitofp requires testing for SSE2 and SSE42 as well (part of the fix for PR26953)

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.

tests don't need -disable-mmx.
