IPA ICF pass 1/N
* gimple-iterator.h (gsi_next_nonvirtual_phi): New function.
* ipa-prop.h (count_formal_params): Global function created from static.
* ipa-prop.c (count_formal_params): Likewise.
* ipa-utils.c (ipa_merge_profiles): Be more tolerant if we merge
profiles for semantically equivalent functions.
* passes.c (do_per_function): If we load body of a function
during WPA, this condition should behave same.
* varpool.c (ctor_for_folding): More tolerant assert for variable
aliases created during WPA.
