I think following what i386 does is reasonable for now.

I'm a bit dubious of the whole Save design - logically it would be cleaner 
if the gcc_options structures were saved just before finish_options, and 
then use of option-changing attributes were to process options with a copy 
of that structure (if this hadn't already been done for that particular 
attribute value), with finish_options and subsequent processing then being 
done for the new copy.  But that would be quite a lot of work, to complete 
a clean separation of option processing working on such structures from 
options processing that actually needs global effects, and then you'd need 
to work out how to represent things for LTO.
