[Runtime] Resolve symbolic references in type mangled name round-trip.
[Runtime] Resolve symbolic references in type mangled name round-trip.

When performing the round-tripping verification for mangled type names,
make sure we resolve symbolic references to something
user-comprehensible that can be meaningfully rem angled.
