[Clang][NFC] Explicitly delete copy ctor and assignment for CGAtomicOptionsRAII (llvm#137275)

shafik · GeorgeARM · commit 23fc363ccc35 · 2025-05-07T16:29:46.000+01:00
Static analysis flagged CGAtomicOptionsRAII as having an explicit
destructor but not having explicit copy ctor and assignment. Rule of
three says we should. We are just using this as an RAII object, no need
for either so they will be specified as deleted.
