Object files have symbol records not aligned to any particular boundary (e.g. 1-byte aligned), while PDB files have symbol records padded to 4-byte aligned boundaries. Since they share the same reading / writing code, we have to provide an option to specify the alignment and propagate it up to the producer or consumer who knows what the alignment is supposed to be for the given container type. Added a test for this by modifying the existing PDB -> YAML -> PDB round-tripping code to round trip symbol records as well as types.
