A couple of notes:
- removed ctx->nip in favour of base->pc_next. Yes, it is annoying,
but didn't want to waste its 4 bytes.
- ctx->singlestep_enabled does a lot more than
base.singlestep_enabled; this confused me at first.

bcdtrunc.: Decimal integer truncate. Given a BCD number in vrb and the
number of bytes to truncate in vra, the return register will have vrb
with such bits truncated.

Since helper_compute_fprf() works on float64 argument, rename it
to helper_compute_fprf_float64(). Also use a macro to generate
helper_compute_fprf_float64() so that float128 version of the same
helper can be introduced easily later.
