rust: Use FLOAT_TYPE_P instead of manual checking

This moves is_floating_point over to using FLOAT_TYPE_P instead
of manually checking. Note before it would return true for all
COMPLEX_TYPE but complex types' inner type could be integral.

Also fixes up the comment to be in more of the GNU style.

Bootstrapped and tested on x86_64-linux-gnu.

gcc/rust/ChangeLog:

	* rust-gcc.cc (is_floating_point): Use FLOAT_TYPE_P
	instead of manually checking the type.
