Sanjay Patel c03d93baa0 [X86] add an exedepfix entry for movq == movlps == movlpd
This is a 1-line patch (with a TODO for AVX because that will affect
even more regression tests) that lets us substitute the appropriate
64-bit store for the float/double/int domains.

It's not clear to me exactly what the difference is between the 0xD6 (MOVPQI2QImr) and 
0x7E (MOVSDto64mr) opcodes, but this is apparently the right choice.

David Blaikie a79ac14fa6 [opaque pointer type] Add textual IR support for explicit type parameter to load instruction
Essentially the same as the GEP change in r230786.

A similar migration script can be used to update test cases, though a few more
test case improvements/changes were required this time around: (r229269-r229278)

import fileinput
import sys
import re

pat = re.compile(r"((?:=|:|^)\s*load (?:atomic )?(?:volatile )?(.*?))(| addrspace\(\d+\) *)\*($| *(?:%|@|null|undef|blockaddress|getelementptr|addrspacecast|bitcast|inttoptr|\[\[[a-zA-Z]|\{\{).*$)")

for line in sys.stdin:
  sys.stdout.write(re.sub(pat, r"\1, \2\3*\4", line))

Simon Pilgrim b2c00f3286 [X86][SSE] Add SSE MOVQ instructions to SSEPackedInt domain
Patch to explicitly add the SSE MOVQ (rr,mr,rm) instructions to SSEPackedInt domain - prevents a number of costly domain switches.

Andrea Di Biagio 23df4e4a2d Teach the DAGCombiner how to fold 'vselect' dag nodes according
to the following two rules:
  1) fold (vselect (build_vector AllOnes), A, B) -> A
  2) fold (vselect (build_vector AllZeros), A, B) -> B
