This CL refactors mkinlcall by extracting the core InlinedCallExpr construction code into a new "oldInline" function, and adds a new "NewInline" hook point that can be overriden with a new inliner implementation that only needs to worry about the details of constructing the InlinedCallExpr. It also moves the delayretvars optimization check into CanInline, so it's performed just once per inlinable function rather than once for each inlined call. Finally, it skips printing the function body about to be inlined (and updates the couple of regress tests that expected this output). We already report the inline body as it was saved, and this diagnostic is only applicable to the current inliner, which clones existing function body instances. In the unified IR inliner, we'll directly construct inline bodies from the serialized representation.
