[Bug lto/41669] New: Infinite recursion trying to build gcc

["espindola at google dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Gcc goes into an infinite recursion trying to build gcc. Reduced test:

cc1 diagnostic.i -quiet -O2 -flto -o diagnostic.s
as -o diagnostic.o diagnostic.s
cc1 ggc-common.i -quiet -O2 -flto -o ggc-common.s
as -o ggc-common.o ggc-common.s
cc1 optabs.i -quiet -O2 -flto -o optabs.s
as -o optabs.o optabs.s

lto1 -quiet  -O2 diagnostic.o ggc-common.o optabs.o -o test.s


The recursion happens in alias.c:717

  set = lang_hooks.get_alias_set (t);
