st/glsl_to_tgsi: fix 64-bit integer bit shifts
Fix a bug that was caused by a type mismatch in the shift count between GLSL and TGSI. I briefly considered adjusting the TGSI semantics, but since both LLVM and AMD GCN require both arguments to be of the same type, it makes more sense to keep TGSI as-is -- it reflects the underlying implementation better. I'm also sending out piglit tests that expose this error. v2: use the right number of components for the temporary register Reviewed-by: Marek Olšák <[email protected]>
