Support implementations where the floating-point division by 0 fails.
* acinclude.m4: added a test to check whether the FP division by 0
fails, and define MPFR_ERRDIVZERO in such a case.
* tests/tests.c: if MPFR_TEST_DIVBYZERO is defined, test whether
there has been a floating-point division by 0 (FE_DIVBYZERO or
FE_INVALID exception).
* tests/tgeneric.c: if MPFR_ERRDIVZERO is defined, disable the
huge and tiny cases.
* tests/t*_{flt,d,ld}.c: if MPFR_ERRDIVZERO is defined, disable
tests involving NaN and infinities.
