LC 8102a0974a AVX: Handle easily broadcastable permutations in VPERMQ
When we have a 3 element identical permutation followed by a single
unique outlier, we can simplify the whole operation into a single
broadcast followed by an insert.

e.g.

0b00'00'00'01
0b00'01'01'01
0b11'11'00'11

are all examples of cases where we can broadcast and then insert.
