These were all using the default 32-bit VALU write class,
but the i64/f64 compares are half rate.
I'm not sure this is really correct, because they are still using
the write to VALU write class, even though they really write
to the SALU.

These are necessary for implementing mem_fence for
OpenCL 2.0.
The VI assembler tests are disabled since it seems to be
using the wrong encoding or opcode.

Adds vcc to output string input for e32. Allows option
of using e64 encoding with assembler.
Also fixes these instructions not implicitly reading exec.

The VOP3 encoding of these allows any SGPR pair for the i1
output, but this was forced before to always use vcc.
This doesn't yet try to use this, but does add the operand
to the definitions so the main change is adding vcc to the
output of the VOP2 encoding.

Although the basic s_load_* instructions happen to use the same
opcode, some of the special case SMRD instructions have
different opcodes.

Summary:
With InstAlias, we don't need to print the _e32 portion of the mnemonic
when we print the $dst operand. This change makes it possible to
include vcc in the asm string when we switch VOPC over to having
implicit vcc defs.

The two-address instruction pass will convert these back to v_mad_f32
if necessary.
