Following D50807, and heading towards D50664, this intermediary change does the following: 1. Upgrade all custom Error types in llvm/trunk/lib/DebugInfo/ to use the new StringError behavior (D50807). 2. Implement std::is_error_code_enum and make_error_code() for DebugInfo error enumerations. 3. Rename GenericError -> PDBError (the file will be renamed in a subsequent commit) 4. Update custom error messages to follow the same formatting: (\w\s*)+\. 5. Keep generic "file not found" (ENOENT) errors as they are in PDB code. Previously, there used to be a custom enumeration for that purpose. 6. Remove a few extraneous LF in log() implementations. Printing LF is a responsability at a higher level, not at the error level.
