Re: i386.record.floating.point.patch : with more testing and assurity

Hi,

Actually, the initial patch which I submitted were using them.
but as I have incorporated Hui's comments I have removed those constants completely.
in the sense I have no longer extended the enumration.

but of course, those registers are recorded as and when required.
e.g. (ffree insn changes FTAG register, so we record it)

Regards,
Oza.
