Victor Umansky 19d8559019 Peephole optimization of ptest-conditioned branch in X86 arch. Performs instruction combining of sequences generated by ptestz/ptestc intrinsics to ptest+jcc pair for SSE and AVX.
Testing: passed 'make check' including LIT tests for all sequences being handled (both SSE and AVX)
