Warning: of course it does something totally different from _mm_insert_epi32!
Copy a to tmp, then insert a single-precision (32-bit) floating-point element from b
into tmp using the control in imm8. Store tmp to result using the mask in imm8[3:0]
(elements are zeroed out when the corresponding bit is set).
