[X86] combineVectorSizedSetCCEquality - allow 256/512-bit vector icmp_ne/eq zero comparisons (#163373)HEADmain
We avoid creating vector movmsk/ptest comparisons with zero if we can
just use scalar OR instead, but this doesn't make sense for 256-bit or
larger vectors which creates a more complex OR chain.
This more closely matches what we do for icmp_ne/eq against non-zero
values.
I'm hoping that we can eventually allow even larger vectors to be
handled with a OR/AND chains - but for now this just allows us to handle
legal 256/512-bit vector widths.
