re PR ipa/77587 (C compiler produces incorrect stack alignment with __attribute__((weak)))
PR target/77587
* cgraph.c (cgraph_node::rtl_info): Pass &avail to
ultimate_alias_target call, return NULL if avail < AVAIL_AVAILABLE.
Call ultimate_alias_target just once, not up to 4 times.
* gcc.dg/pr77587.c: New test.
* gcc.dg/pr77587a.c: New file.
