Let the compiler know that the inline assembly in
zend_safe_address()clobbers the flags register.We need to add
ccin the clobber list for aarch64 (ADDSaffect the condition flags), andxerfor powerpc64 (ADDC,ADDZEaffect the Fixed point exception register AKAxer).i386, x86_64, and arm were already correct. Other inline assembly blocks seem correct.
I didn't reproduce the issue on powerpc64, but the change was tested at https://github.com/php/php-src/actions/runs/21404066744/job/61623034776.
