Introduce a new pass MandatoryTempRValueElimination, which works as the original TempRValueElimination, except that it does not remove any alloc_stack instruction which are associated with source variables. Running this pass at Onone helps to reduce copies of large structs, e.g. InlineArrays or structs containing InlineArrays. Copying large structs can be a performance problem, even at Onone. rdar://151629149
