Also delete unary_def_via_fp32.inc. There are small changes in amdgcn--amdhsa.bc due to vector conversion is scalarized, e.g. %2 = fpext <4 x half> %0 to <4 x float> %3 = extractelement <4 x float> %2, i64 0 %4 = tail call float @llvm.fabs.f32(float %3) -> %2 = extractelement <4 x half> %0, i64 0 %3 = tail call half @llvm.fabs.f16(half %2) %4 = fpext half %3 to float
