We have Error.cpp/.h which contains some code for working with error codes. In fact we use Error/Expected<> almost everywhere already and we can get rid of these files. Note: a few places in the code used readobj specific error codes, e.g. `return readobj_error::unknown_symbol`. But these codes are never really used, i.e. the code checks the fact of a success/error call only. So I've changes them to `return inconvertibleErrorCode()` for now. It seems that these places probably should be converted to use `Error`/`Expected<>`. Differential revision: https://reviews.llvm.org/D86772
