Craig Topper 853a8d9ffc [AVX512] Don't create SHRUNKBLEND SDNodes for 512-bit vectors
There are no 512-bit blend instructions so we shouldn't create SHRUNKBLEND for them.

On a side note, it looks like there may be a missed opportunity for constant folding TESTM when LHS and RHS are equal.

This fixes PR34139.
