[X86] combinePTESTCC - fold PTESTZ(X,SIGNMASK) -> VTESTPD/PSZ(X,X) on AVX targets (#165676)
If the PTEST is just using the ZF result and one of the operands is a
i32/i64 sign mask we can use the TESTPD/PS instructions instead and
avoid the use of an extra constant.
Fixes some codegen identified in #156233
