Craig Topper e30cb00dc0 [AVX-512] Add subvector insert and extract to load/store folding tables.

Craig Topper b880ad3a71 [AVX-512] Add support for commuting masked instructions in findCommutedOpIndices. The default implementation doesn't skip the mask input or the preserved input.

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 2c51c74d52 [AVX-512] Add 512-bit logical operations to load folding tables. Add avx512f stack folding test and move some tests from the avx512vl test.
