Claiming a mismatch is always in a precompiled header is wrong and misleading as a mismatch can happen in any provided AST file. Emitting a path for a file with a problem allows to disambiguate between multiple input files. Use generic term "AST file" because we don't always know a kind of the provided file (for example, see `ASTReader::readASTFileControlBlock`). rdar://65005546
