* Remove RegisterPreservingCC. It was unused. * Remove DefaultCC from the runtime. The distinction between C_CC and DefaultCC was unused and inconsistently applied. Separate C_CC and DefaultCC are still present in the compiler. * Remove function pointer indirection from runtime functions except those that are used by Instruments. The remaining Instruments interface is expected to change later due to function pointer liability. * Remove swift_rt_ wrappers. Function pointers are an ABI liability that we don't want, and there are better ways to get nonlazy binding if we need it. The fully custom wrappers were only needed for RegisterPreservingCC and for optimizing the Instruments function pointers.
