The key being added to respective maps which facilitate diffing of
unreferenced user defined types was earlier the linker set key. The
unique id should be used instead. This is because linker set keys for C
and C++ types can be the same, but their unique id's cannot. Thus,
having linker set keys as a key leaves open the possibility of false
type aliasing, whereas the unique id does not.

passes.

Previously, the tests mainly exercised header-abi-diff.
After this change, checked-in reference dumps are compared with
generated dumps. This allows us to:
- get header-abi-dumper and header-abi-linker involved in testing
better.
- Know about any incompatbile message format changes made
inadvertently.
Test: tests/test.py; all tests pass.

1) We do not involve the build system to create test reference dumps. Symbols
in tests, are faked through version scripts to avoid checking in prebuilt .so
test files.
2) Also add a script to create reference abi dumps.
3) Fix a comment in ast_processing.cpp
Test: Run tests/test.py, all tests run and pass on generic arm64, mips64
and x86_64 builds.
