Revert "InstCombine: Turn mul.with.overflow(X, 2) into the cheaper add.with.overflow(X, X)"
...
It's better to do this in codegen, mul.with.overflow(X, 2) is more canonical because it has only one use on "X".

This is a simplified (and superior) implementation of __invoke, __invokable and __invoke_of. It is superior in that __invoke now handles reference qualified member functions whereas the previous implementation did not. And it simply has less infrastructure in its implementation.
