Diff to previous 1.20 (colored)

Fix logic for FI, FR, and FPRF fields of FPSCR.

They are not sticky bits and updated by arithmetic and round
insns at the same time.

Comparison insns update only FPCC sub-field of FPRF.

For other insns, these field are left untouched.

Also, for single-precision insns, exception bits should be set by
the first fpu_implode(), which rounds the value to float.

Exceptions are fcti{w,d}{,z}; FPSCR[FPRF] becomes undefined,
according to Power ISA. We do not overwrite this field for
these insns at the moment.
