To validate this code, I ran piglit -t vs quick.tests with the "go spill
everything" debugging code enabled. There was only one regression:
glsl-vs-unroll-explosion simply ran out of registers. This should be
fine in the real world, since no one actually spills every single
register.
NOTE: This is a candidate for the 9.0 branch. Even if it proves to have
bugs, it's likely better than simply failing to compile.
