Joe Groff	8ac1bda817	SIL: Move retain/release/destroy helpers onto SILBuilder. ... Add a convenience SILModule::getTypeLoweringInfo forwarder, and move the emitRetainRValue and emitReleaseRValue helpers from SILGenFunction to SILBuilder so they're more readily available to non-SILGen passes. Add an emitDestroyAddress helper that emits nothing, destroy_addr, or load + release based on the value semantics of the referenced type. Swift SVN r6431	2013-07-21 18:39:56 +00:00
