This also fixes the piglit depth-tex-compare test!  Neither softpipe nor
llvmpipe were clamping the texture coordinate to [0,1], per the spec.  llvmpipe
still doesn't pass depth-tex-compare completely (for ==, != cases), but I
believe that's a defect in the test itself.

Softpipe still has other issues with shadow compare w.r.t. linear vs bilinear
filtering but that's less important than this fix.

Does this bug report only pertain to the softpipe driver?  If so, please test
Mesa/master with this patch (commit 0eef561a5bb10df343837d58d37d5c0d5b708243)
and close.
