    M clang/lib/Serialization/ASTReader.cpp

  Log Message:
  -----------
  [Modules] Change result of reading AST block to llvm::Error instead

Reading the AST block can never fail with a recoverable error as modules
cannot be removed during this phase. Change the return type of these
functions to return an llvm::Error instead, ie. either success or
failure.

NFC other than the wording of some of the errors.
