[PATCH] Remove atomic_compare_and_exchange_bool_rel.

[Torvald Riegel]

Removing this operation and the matching (unused) catomic_ operation
seemed to be easier than fixing powerpc's definition of it, only for it
to be removed anyway in the future.  There were just three call sites of
it.

Tested on x86_64-linux.  Lei Xu, could you test on Power?
