Craig Topper 00aecd97bf [AVX-512] Add execution domain fixing for logical operations with broadcast loads. This builds on the handling of masked ops since we need to keep element size the same.

Craig Topper 8f6827c945 [AVX-512] Add patterns to select masked logical operations if the select has a floating point type.
This is needed in order to replace the masked floating point logical op intrinsics with native IR.

Craig Topper 0f8fb47637 [AVX-512] Add test cases for masked floating point logic operations with bitcasts between the logic ops and the select. We don't currently select masked operations for these cases.
Test cases taken from optimized clang output after trying to convert the masked floating point logical op intrinsics to native IR.

Craig Topper abe80cc04d [AVX-512] Promote AND/OR/XOR to v2i64/v4i64/v8i64 even when we have AVX512F/AVX512VL.
Previously we weren't creating masked logical operations if bitcasts appeared between the logic operation and the select. The IR optimizers can move bitcasts across logic operations and create these cases. To minimize the number of cases we need to handle, this change promotes all logic ops to an i64 vector type just like when only SSE or AVX is available.

Unfortunately, this also has the consequence of making it difficult to select unmasked VPANDD/VPORD/VPXORD in all the cases it was previously used. This is the cause of most of the test change. This shouldn't result in any functional change though.

Craig Topper 8046e2033e [AVX-512] Add tests to show that we don't select masked logic ops if there are bitcasts between the logic op and the select.
This is taken from optimized IR of clang test cases for masked logic ops.

Craig Topper 92a4ff1294 [AVX-512] Add support for execution domain switching masked logical ops between floating point and integer domain.
This switches PS<->D and PD<->Q.

Craig Topper c48c029610 [AVX-512] Fix duplicate column in AVX512 execution dependency table that was preventing VMOVDQU32/VMOVDQA32 from being recognized. Fix a bug in the code that stops execution dependency fix from turning operations on 32-bit integer element types into operations on 64-bit integer element types.

Craig Topper 7ee070e7bc [AVX512] Add support for 512-bit ANDN now that all ones build vectors survive long enough to allow the matching.

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))
