I think the insn-flags.h macros and actual insn conditions are checked when the
corresponding function is current, and at that point opt_for_fn (cfun,
optimize_size) should be the same as optimize_size.  Even the set_cfun hook
first sets the option and then tries to initialize optab and compares it
against the global one.
