description:
pull up 1.4 (approved by thorpej):
>Add fpu emulation instrumentation and fixup FCMP and FCMPE emulation for v9.
>And rename the 128-bit `x' routines to `q' to match v9 terminology:
>        i - 32-bit int
>        x - 64-bit int
>        s - 32-bit fp
>        d - 64-bit fp
>        q - 128-bit fp
