Add missing final paragraph of explaination about x86 FP trickery.
relevant register. There are only six %fake registers because 2 are
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.
