Implement Complex#<=> so that it is usable as an argument when
calling <=> on objects of other classes (since #coerce will coerce
such numbers to Complex). If the complex number has a zero imaginary
part, and the other argument is a real number (or complex number with
zero imaginary part), return -1, 0, or 1. Otherwise, return nil,
indicating the objects are not comparable.
Fixes [Bug #15857]
Cannonicalize resultant real and imaginary parts when complex number
divided by non-complex number.

This fixes the incompatibility (maybe unintentionally) introduced by
removal of `#ifndef PRESERVE_SIGNEDZERO` guards in f_add, f_mul, and
f_sub functions in r62701. [Bug #15491] [ruby-core:90843]

* complex.c (rb_complex_new_polar): renamed with _new to clarify
that it creates a new instance, but is not an instance method.
* complex.c (rb_complex_polar): deprecated.

returns more precise value in right angle cases.

form.

for imaginary part, in documentation for Complex#{finite?,infinite?}.

Support `exception:` keyword argument in `Kernel#Complex()`.
If `exception:` is `false`, `Kernel#Complex()` returns `nil` if the given
value cannot be interpreted as a complex value.
The default value of `exception:` is `true`.
This is part of [Feature #12732].

Fixnums can be compared by object values themselves only.
Addition/subtraction/mulplication of fixnum 0 do not affect the
sign.
