Bug description

ocamlopt generates a unique quadword constant for every floating point constant within a function. The attached patch merges common floating point constants for the amd64 and i386 target (other ports can use a similar trick, of course, but I don't have the hardware to test, nor the knowledge to be sure there are no other constraints on the floating point constants).

New patch, which merges floating-point constants for i386/amd64 per-module instead of per-function.
