bpf: handle anonymous members in CO-RE reloc [PR106745]
The old method for computing a member index for a CO-RE relocation
relied on a name comparison, which could SEGV if the member in question
is itself part of an anonymous inner struct or union.
This patch changes the index computation to not rely on a name, while
maintaining the ability to account for other sibling fields which may
not have a representation in BTF.
gcc/ChangeLog:
PR target/106745
* config/bpf/coreout.cc (bpf_core_get_sou_member_index): Fix
computation of index for anonymous members.
gcc/testsuite/ChangeLog:
PR target/106745
* gcc.target/bpf/core-pr106745.c: New test.
