0d4a35d5 - IR: Remove llvm.convert.to.fp16 and llvm.convert.from.fp16 intrinsics (#174484)

IR: Remove llvm.convert.to.fp16 and llvm.convert.from.fp16 intrinsics (#174484) These are long overdue for removal. These were originally a hack to support loading half values before there was any / decent support for the half type through the backend. There's no reason to continue supporting these, they're equivalent to fpext/fptrunc with a bitcast. SelectionDAG stopped translating these directly, and used the bitcast + fp cast since f7a02c17628e825, so there's been no reason to use these since 2014.
