I don't like the patch too much. Why are you removing the cfun->optabs stuff?
set_cfun is called pretty often, e.g. during IPA switching to various functions
and back, when you remove cfun->optabs, it will constantly need to recompute
the optabs (quite expensive operation) if switching between mips16 vs.
non-mips16 functions with different optimization attributes. The base_optabs
stuff is fine, but I'd just remove the ggc_free and in
invoke_set_current_function_hook
restore the saving of the computed optabs into cfun->optabs and using it if
already set.
