Bump minimum MPFR version to 3.1.0
Bump the minimum MPFR version to 3.1.0, released 2011-10-03. With this
requirement one can still build GCC with the operating system provided
MPFR on old but still supported operating systems like SLES 12 (MPFR
3.1.2) or RHEL/CentOS 7.x (MPFR 3.1.1).
This allows removing some code in the Fortran frontend, as well as
fixing PR 91828.
