x86: Replace all sse instructions with vex equivilent in avx+ files
Most of these don't really matter as there was no dirty upper state but we should generally avoid stray sse when its not needed. The one case that really matters is in svml_d_tanh4_core_avx2.S: blendvps %xmm0, %xmm8, %xmm7 When there was a dirty upper state. Tested on x86_64-linux
