Adding unit tests turned out to be a little complicated.
There were already a couple of unit tests in file _lldb/unittests/Expression/DWARFExpressionTest.cpp_ that actually were failing with these changes, so I replaced them.

Not sure what to do with the old tests, I don't think a `DW_OP_WASM_location` might ever be located in an ELF file, given that with "split symbols" Wasm uses the Wasm file format both for the file with the code and for the file with symbols. (Tested with emscripten).
