Fix stack overflow with autofdo (PR83355)

g++.dg/bprob* is failing currently with autofdo.

Running in gdb shows that there is a very deep recursion in get_index_by_decl until it
overflows the stack.

PR gcov-profile/83355
* auto-profile.c (string_table::get_index_by_decl): Don't
recurse when abstract origin points to itself.
