RFR: 8338471: Assert deleted methods not returned by CallInfo [v2]

[Coleen Phillimore]

> CompiledIC can get old methods, but it can't get deleted methods for itable and vtable calls, so add a guarantee and asserts that this cannot happen before dereferencing.  Removed unused function and unnecessary methodHandle operator.
> Tested with tier1-4 and 8 which does a lot of redefinition.
