RAII auto_mpfr and autp_mpz
The following adds two RAII classes, one for mpz_t and one for mpfr_t
making object lifetime management easier. Both formerly require
explicit initialization with {mpz,mpfr}_init and release with
{mpz,mpfr}_clear.
I've converted two example places (where lifetime is trivial).
* system.h (class auto_mpz): New,
* realmpfr.h (class auto_mpfr): Likewise.
* fold-const-call.cc (do_mpfr_arg1): Use auto_mpfr.
(do_mpfr_arg2): Likewise.
* tree-ssa-loop-niter.cc (bound_difference): Use auto_mpz;
