`RawComments` are sorted by comparing underlying `SourceLocation`'s. This is done by comparing `FileID` and `Offset`; when the `FileID` is the same it means the locations are within the same TU and the `Offset` is used. FileID, from the source code: "A mostly-opaque identifier, where 0 is "invalid", >0 is this module, and <-1 is something loaded from another module.". That said, when de-serializing SourceLocations, FileID's from RawComments loaded from other modules get negative IDs where previously they were positive. This makes imported RawComments unsorted, leading to a wrong merge with other comments from the current TU. Fix that by sorting RawComments properly after de-serialization and before merge. This fixes an assertion in `ASTContext::getRawCommentForDeclNoCache`, which fires only in a debug build of clang.
