[MPFR] Fix regression on 32-bit host systems

When converting parts of the mantissa to MPFR, we need to make sure to do
an *unsigned* conversion.  Since we convert at most 32 bits at a time,
stored in an unsigned long, this doesn't matter on systems where "long"
is larger than 32 bits.  But on systems where it is 32 bits, we can get
conversion errors.

	* target-float.c (mpfr_float_ops::from_target): Use mpfr_set_ui
	instead of mpfr_set_si to convert mantissa bits.
