not all constants though (power of 2 are fine) for an example 16:
        mr r12,r3
        srawi r11,r3,31
        srawi r9,r11,31
        srawi r10,r11,31
        srwi r10,r9,28
        li r9,0
        addc r12,r10,r4
        adde r11,r9,r3
        srwi r4,r12,4
        insrwi r4,r11,4,0
        srawi r3,r11,4


Confirmed.
