Okay. The only caveat being, if someone actually *wanted* to enable
float for swrast, this would prevent them from going down that path.

ajax on #dri-devel pointed out that some piglit tests go from pass to
fail instead of being skipped as a result of the above patch since the
piglit tests are done with swrast and run very poorly without float
enabled.
