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.

Get rid of some bogus patterns for X86vzmovl. Don't create VZEXT_MOVL
...
nodes for vectors with an i16 element type. Add an optimization for
building a vector which is all zeros/undef except for the bottom
element, where the bottom element is an i8 or i16.
