Instead of calling `require()` every instruction, call it once per pass.
Even though the defs are cached (i.e. we are not re-calculating them every
instruction), this prevents the extra check and the call to analysis
validation.

- brw_lower_3src_null_dest: Allocating a new destination, so include
INSTRUCTION_DATA_FLOW class.
- brw_lower_alu_restriction: Removing instruction, so include
INSTRUCTION_IDENTITY. No details are changed so remove
INSTRUCTION_DETAIL.
- brw_lower_vgrfs_to_fixed_grfs: Changing source and destination
numbers, so include INSTRUCTION_DETAIL.
- brw_lower_send_gather: Insert new instructions (scalar register) and
change sources and other information on existing ones. So include
INSTRUCTION_DETAIL and INSTRUCTION_IDENTITY. Promote to INSTRUCTIONS.
- brw_opt_eliminate_find_live_channel: Can change source, so include
INSTRUCTION_DATA_FLOW.
- brw_opt_copy_propagation_defs and brw_opt_cse_defs: Both can remove
instructions, so include INSTRUCTION_IDENTITY. Promote to
INSTRUCTIONS.
- brw_opt_saturate_propagation: Instruction can have `sat` modified,
and operands can have type modified, so include INSTRUCTION_DETAIL.
