Disable AliasMethod direct binding for now

The logic here does not reflect recent changes to how alias methods
are dispatched, and does not properly handle several things:

* The compoundName is not passed through
* The actual implementation class may not get passed in
* Cases that require an implementer search are not handled

The combination of these leads to issues when aliased methods are
bound by indy JIT logic, so we will disable this for now and fix it
properly in JRuby 10.1.

Fixes jruby#8944
