da709f5b - [X86] combinePTESTCC - fold PTESTZ(X,SIGNMASK) -> VTESTPD/PSZ(X,X) on AVX targets (#165676)

[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
