cmd/compile: add indexed memory modification ops to amd64

name            old time/op  new time/op  delta
Modify-16        404ns ± 1%   365ns ± 1%  -9.73%  (p=0.000 n=10+10)
ConstModify-16   407ns ± 0%   385ns ± 2%  -5.56%  (p=0.000 n=9+10)

Seems to generally help generated code.

Binary size change is in the noise.
