[PATCH] ipa: "naked" attribute implies "noipa" attribute

["Martin Liška" <mliska@suse.cz>]

Hi.

This is a first part fixing the PR. It makes sense making "naked" functions "noipa".
What's missing is IPA MOD pass support where the pass should not optimize fns
with "noipa" attributes.

@Honza: Can you please implement that?

Patch can bootstrap on x86_64-linux-gnu and survives regression tests.

Ready to be installed?
Thanks,
Martin
