glsl: Lower vector_extracts to swizzles after lower_vector_derefs.
lower_vector_derefs can produce new vector_extract operations. Neither i965 nor st_glsl_to_tgsi can handle them, so we'd best convert them to swizzles. Together with the previous patch, this fixes assertion failures in GLideN64, as well as a new Piglit test which reproduces the issue: spec/glsl-1.10/compiler/vector-dereference-in-dereference.frag Cc: [email protected] Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=95164 Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Ian Romanick <[email protected]>
