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.

Remove the unaligned load intrinsics in favor of using native unaligned loads.
...
Now that we have a first-class way to represent unaligned loads, the unaligned
load intrinsics are superfluous.
First part of <rdar://problem/8460511>.

improve the setcc -> setcc_carry optimization to happen more
...
consistently by moving it out of lowering into dag combine.
Add some missing patterns for matching away extended versions of setcc_c.

AVX doesn't support mm operations neither its instrinsics.

The AVX versions of PALIGN and PABS* should only exist for
128-bit. Remove the unnecessary stuff.
