Make _Complex_I a proper float _Complex when using GCC 4.2.

It turns out our GCC has quite an interesting bug:

	typeof(1.0fi) != float _Complex
	typeof((float _Complex)1.0fi) != float _Complex
	typeof((float _Complex)1.0i) == float _Complex

In other words: if casting to an equal size, GCC seems to take a
shortcut. By casting down from a double to a float, GCC doesn't take
this shortcut, yielding the proper type.

To prevent foot-shooting, add a _Static_assert() to guarantee that
_Complex_I is always a float _Complex. I'm not going to MFC this part of
the diff.

MFC after:	2 weeks
