Today, I checked whether we can take advantage of this optimization for 
floats, but I didn't see any load-modify-store instructions in the x86 
instruction set (neither x87, nor SSE/AVX). Are there any floating point 
instructions on any architecture, that we support, that does 
load-modify-store (i.e. modify-in-place) of a memory operand?
