I would use some test from gcc/testsuite/gcc.dg/ipa/ipa-sra-*.c, add
the attribute and negate the scan-dump test.

I think you also want to disable optimizations we do about local functions

Hi!
So here is a proof of concept of an attribute that disables inlining,
cloning, ICF, IPA VRP, IPA bit CCP, IPA RA, pure/const/throw discovery.
Does it look reasonable? Anything still missing?
No testsuite coverage yet, I bet we'd want to check for all those opts and
