Commit message should have been

lib/56832: __atomic_compare_exchange[_n] is wrong on non-mainstream

Make the implementation match the documentation wrt 'expected'

This built-in function implements an atomic compare and exchange
operation.This compares the contents of *ptr with the contents of
*expected. If equal, the operation is a read-modify-write operation that
writes desired into *ptr. If they are not equal, the operation is a read
and the current contents of *ptr are written into *expected.
