No subject

    This extension provides a method to pre-assign attribute locations to
    named vertex shader inputs and color numbers to named fragment shader
    outputs.

This was accidentally implemented for fragment shader inputs.  This
patch fixes it to apply to fragment shader outputs.

Fixes piglit tests
spec/ARB_explicit_attrib_location/1.{10,20}/compiler/layout-{01,03,06,07,08,09,10}.frag

Breaks piglit tests
spec/ARB_explicit_attrib_location/1.{10,20}/compiler/in-04.frag, which
appear to be incorrect (they specify "expect_result: pass", but
comments in the tests make it clear that they are expected to fail).

I'll submit a patch to piglit to correct the two broken tests.
