I do not know about Go alternate stacks but the checks for example already
supports gcc -fsplit-stack.  More such features should be rather implemented
than to drop UNWIND_INNER_ID.  Could not be GDB taught about thue alternate
stack?

Looping backtraces are a pain for both interactive and automatic bugreporting,
it is already a TODO item GDB should better handle f() { f(); } type stack
overflows as it proven less GDB-savvy users fail to debug such issue in GDB.
