fc0fc768 - [X86] Finally handle target of __builtin_ia32_cmp[p|s][s|d] from avx into sse/sse2/avx (#84136)

[X86] Finally handle target of __builtin_ia32_cmp[p|s][s|d] from avx into sse/sse2/avx (#84136) This patch relands #67410 and fixes the cmpfail below: #include <immintrin.h> __attribute__((target("avx"))) void test(__m128 a, __m128 b) { _mm_cmp_ps(a, b, 14); } According to Intel SDM, SSE/SSE2 instructions cmp[p|s][s|d] are supported when imm8 is in range of [0, 7]
