i965/sf: Reset flag_value to 0xff before emitting SF subroutines.
When compiling any of the SF program variants, flag_value starts off as 0xff and will be modified when generating code. brw_emit_anyprim_setup emits several subroutines, saving and restoring flag_value across each of them. Since it starts out as 0xff, this is equivalent to simply setting it to 0xff at the start of each subroutine. Resetting the value makes more logical sense; each subroutine doesn't know whether one of the others even executed, much less what it did to the flag register. This also lets us to drop the brw_set_predicate_control_flag_value call from brw_init_compile: predicate is already initialized to BRW_PREDICATE_NONE by the memset, and the value of flag_value is irrelevant (as it's only used by the SF compiler).
