i965: Add a brw_load_register_reg64 helper.
It appears that we can't do this in a single command (like we do for MI_LOAD_REGISTER_IMM) - the Skylake simulator gets rather grumpy about the command length if I try to combine them. No matter. Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Jordan Justen <[email protected]>
