ARM: Make "SMC" instructions conditional on new TrustZone architecture feature. These instructions aren't universally available, but depend on a specific extension to the normal ARM architecture (rather than, say, v6/v7/...) so a new feature is appropriate. This also enables the feature by default on A-class cores which usually have these extensions, to avoid breaking existing code and act as a sensible default. llvm-svn: 179171
