Hi Tim,

Despite the name, this isn't a precise keyword test.  It's just verifying that
reflect() works with various floating point values.

The test does "out = reflect(in0, in1)".

It looks like before we generated:

    ffma -2.0 (mul (mul ssbo10 ssbo13) ssbo13) ssbo10

And now we generate:

    ffma (mul (mul ssbo10 2.0) ssbo13) ssbo13 ssbo10

which is having trouble with some extreme values.  CC'ing Jason too.
