clang in CodeGenFunction::EmitBuiltinExpr() considers embedded intrinsic names before calling EmitTargetBuiltinExpr(). Since we want these intrinsics to be emitted with range metadata we need to do it in EmitAMDGPUBuiltinExpr(called by EmitTargetBUiltinExpr). The embedded names need to be removed, otherwise the Emit* functions won't run.
