[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.

Had to update a stack folding test to clobber the other 16 registers since this now made them get used instead of spilling.
