Interesting, only codegen changes I saw with this patch are related to ipa-icf
no longer
merging functions returning void because it makes bogues alias_set querries I
am about
to fix incrementally (and I even got no code changes on tramp3d with -fno-icf).
I will check if these two testcases depends on ICF to pass with LTO.
Anyway hope early debug to get us out of trouble here ;)
