merge revision(s) 60040,60188: [Backport #14014]
complex.c: no overflow
* complex.c (rb_complex_finite_p): get rid of overflow and
unnecessary multiplication.
test_complex.rb: NaN Complex
* test/ruby/test_complex.rb (test_finite_p): assertions for NaN
Complex. NaN is not an infinite nor a finite number.
