getSymbolSize was recently added to WasmObjectFile and has correct sizes for most symbol types. This makes llvm-symbolizer correctly symbolize addresses in the middle of the symbol. When reworking the test I also noticed that the DWARF info seems to be wrong for the first instruction in each function. I noted that in the test comments but didn't attempt to fix here.
