Remove alias set comparison.
2019-10-30 Martin Liska <mliska@suse.cz>
* ipa-icf-gimple.c (func_checker::compatible_types_p):
Do not compare alias sets. It's handled by operand_equal_p.
2019-10-30 Martin Liska <mliska@suse.cz>
* c-c++-common/Wstringop-truncation-4.c: Disable IPA ICF.
* gcc.dg/tree-ssa/pr64910-2.c: Likewise.
* gcc.dg/tree-ssa/pr79352.c: Likewise.
