Strict fp-to-int and int-to-fp conversions can be handled in the same way that
the non-strict versions are (by using the appropriate instruction or converting
to a function call when we have no instruction).

This gets selected to the appropriate fcvt instruction. Handling from there on
isn't fully correct yet, as we need to model fcvt reading and writing to fpsr
and fpcr.

These become STRICT_FCMP and STRICT_FCMPE, which then get selected to the
corresponding FCMP and FCMPE instructions, though the handling from there on
isn't fully correct as we don't model reads and writes to FPCR and FPSR.
