Add missing final paragraph of explaination about x86 FP trickery.

needed for the translation, and x86 has 8 in total.
The translation is inefficient but is simple and it works. A cleverer
translation would handle a sequence of insns, simulating the FP stack
contents, would not impose a fixed mapping from %fake to %st regs, and
hopefully could avoid most of the redundant reg-reg moves of the
current translation.
