    glsl_to_tgsi: Use the GLSL compiler's new remove-output-reads pass.

    The existing glsl_to_tgsi::remove_output_read pass did not work properly
    when indirect addressing was involved; this commit replaces it with a
    lowering pass that occurs before TGSI code generation.

    Fixes varying-array related piglit tests.
