Finishes cleanups that I started in other commits in this branch. * Use common.linkage for all exports instead of redoing the logic in each file. * Remove pointless `@setRuntimeSafety` calls. * Avoid redundantly exporting multiple versions of functions. For example, if PPC wants `ceilf128` then don't also export `ceilq`; similarly if ARM wants `__aeabi_ddiv` then don't also export `__divdf3`. * Use `inline` for helper functions instead of making inline calls at callsites.
