pub fn _mm_fixupimm_ss(a: __m128, b: __m128, c: __m128i, IMM8: i32) -> __m128

Fix up the lower single-precision (32-bit) floating-point elements in a and b using the lower 32-bit integer in c, store the result in the lower element of dst, and copy the upper 3 packed elements from b to the upper elements of dst. imm8 is used to set the required flags reporting.
