Floating point intrinsics working on PowerPC

The compiler now inlines machine code for floating point operations instead of calling the runtime. This results in a performance improvement on my 2.5 Ghz PowerPC G5:

Benchmark	Before	After
Mandelbrot	10.5	5.4
Raytracer	61.1	41

Here are the x86 results (Pentium 4 1.8 GHz):

Benchmark	Before	After
Mandelbrot	8.7	4.3
Raytracer	44.3	33.2

The Before column is 0.81, the After column is 0.82, and times are in seconds.
Yes, a five year old box beats my brand new G5, but I suspect this is because my compiler doesn't do instruction scheduling.
Bigger gains will come as the higher levels of the compiler improve, resulting in more inlining.
