complex.c: optimize f_negate

Browse source 
* complex.c (f_negate): optimize for special numeric types.

* complex.c (nucomp_expt): use rb_int_uminus instead of f_negate for
  fixnum value.

* internal.h (rb_float_uminus, rb_rational_uminus): exported.

* numeric.c (rb_float_uminus): rename from flo_uminus.

* rational.c (rb_rational_uminus): rename from nurat_negate, and add
  assertion for the parameter.
