nir/instr_set: remove unnecessary check in nir_instrs_equal()
This was originally added to nir_instrs_equal() instead of nir_instr_can_cse() incorrectly, but this was fixed when moving to the instruction set API (as it had to be, otherwise hashing wouldn't work). Now, this is dead code since instr_can_rewrite() will only return true for texture instructions that use an index, so we can turn the check into an assert. This also means that now nir_instrs_equal(instr, instr) will always return true unless it assert-fails. Reviewed-by:Jason Ekstrand <jason.ekstrand@intel.com> Signed-off-by:
