Target FP: Make use of MPFR if available
...
This second patch introduces mfpr_float_ops, an new implementation
of target_float_ops. This implements precise emulation of target
floating-point formats using the MPFR library. This is then used
to perform operations on types that do not match any host type.
Note that use of MPFR is still not required. The patch adds
a configure option --with-mpfr similar to --with-expat. If use of
MPFR is disabled via the option or MPFR is not available, code will
fall back to current behavior. This means that operations on types
that do not match any host type will be implemented on the host
long double type instead.
A new test case verifies that we can correctly print the largest
__float128 value now.
