The patch fixes broken SHADOWCUBE handling - coords[3] was never defined
and caused asserts in LLVM, but now I noticed that the patch also adds
unnecessary operation for CUBE. It has no regressions though and fixes
some piglit tests for SHADOWCUBE.

I'll try to add cube arrays support and improve other things before
resending.
