The problem is in code introduced by Bernd in IRA and caller-saves.c in
2012. It is basically an optimization for functions returning always the
same result as one argument (e.g. memcpy returning 1st argument).

Attached v2 patch implements the same approach in all alias.c places

for the first patch, it is actually easier to repost the old patch with some
new testcases. That doesn't mean it has to go in all at once, but you can
comment on various things. If that's a problem I'll separate them and
altogether. The
MEM_READONLY_P successfully supersedes const_alias_set functionality,
and this is also confirmed by the removal of the second
varasm_init_once call in the Go frontend. In an off-list discussion,
Ian agrees that attached patch should also fix the problem.
