No branch protection metadata unless enabled Even if we emit metadata disabling branch protection, this metadata may conflict with other modules (e.g. during LTO) that have different branch protection metadata set. This is an unstable flag and feature, so ideally the flag not being specified should act as if the feature wasn't implemented in the first place. Additionally this PR also ensures we emit an error if `-Zbranch-protection` is set on targets other than the supported aarch64. For now the error is being output from codegen, but ideally it should be moved to earlier in the pipeline before stabilization.
