Infinite recursion in resolve_function_name

[benjaminRomano]

Background

We are processing DWARF symbols for one of our .so files and hitting infinite recursion on function name resolution.

Potentially, this is a bug in DWARF symbols generation from the Android NDK Toolchain. Effectively, there is a self-reference loop, but with one layer of indirection so the existing fix for this does not work: #202.

Potential fixes

1. Add a depth check to prevent infinite recursion -- I'm not sure if this is necessary or not. I don't know if there is at-most one level of indirection or arbitrary amounts possible.
2. Check if the next reference to inspect is not the same as the prior reference: Avoid infinite recursion on indirect self-references #836
