Craig Topper a6054328e8 [X86] Teach the execution domain fixing tables to use movlhps inplace of unpcklpd for the packed single domain.
MOVLHPS has a smaller encoding than UNPCKLPD in the legacy encodings. With VEX and EVEX encodings it doesn't matter.

Sanjay Patel d3173740fd [x86] auto-generate complete checks for tests; NFC
These all used 'CHECK-NOT' which isn't necessary if we have complete checks.
There were also several over-specifications in the RUN params such as CPU model or OS requirement

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))

Craig Topper a4d411cb1b Don't try to match 'unpackl/h v, v' for 32xi8 and 16xi16 when only AVX1 is supported. Fix 'unpackh v, v' for 256-bit types to understand 128-bit lanes.

Craig Topper d65a444478 Remove 256-bit specific node types for UNPCKHPS/D and instead use the 128-bit versions and let the operand type disinquish. Also fix the load form of the v8i32 patterns for these to realize that the load would be promoted to v4i64.

Bruno Cardoso Lopes 6963062a99 Use fp unpack instructions to unpack int types. Until we have AVX2, this
is the best we can do for these patterns. This fix PR10554.
