  Changed paths:
    M clang/docs/ReleaseNotes.rst
    M clang/lib/Sema/SemaDeclCXX.cpp
    M clang/test/SemaCXX/warn-unused-private-field.cpp

  Log Message:
  Clang: Don't warn about unused private fields of types declared maybe_unused

The compiler should not warn on code such as:

  class [[maybe_unused]] MaybeUnusedClass {};
  class C {
    MaybeUnusedClass c;

Patch based on comments on the bug by Shafik and Aaron.

Fixes #61334
