Arm64's implementation of `TurboAssembler::Abort()` supports printing the
bailout reason to the standard output without calling to the runtime. For this
to work, we need access to the host's printf function so we can call it
directly. In the general case, `Abort` does call the runtime, however, we cannot
do it if we want to abort from inside CEntryStub.
