  Changed paths:
    M clang/lib/AST/ASTContext.cpp
    M clang/lib/Sema/SemaConcept.cpp

  Log Message:
  -----------
  Stop modifying trailing return types.

This change reverts the functional change from D144626 but retains its
test. Instead of dealing with the possibility that a trailing requires
clause might have been rewritten into some other incorrect form, just
stop rewriting it.

No functionality changes intended.
