Avoid mpz for some common timestamp cases
Performance problem reported by Gerd Möllmann and Mattias Engdegård in:

* src/timefns.c (CFORM_SECS_ONLY): The exact tv_nsec value is now
ignored if nonnegative (i.e., the only thing that matters is that
it’s nonnegative).
(decode_time_components): Use intmax_t instead of mpz arithmetic
if the tick count fits. Add another ‘default: eassume (false);’
so that the revised code pacifies --enable-gcc-warnings with GCC
11.4.0 on x86-64.
