RFR(s): 8169206: TemplateInterpreter::_continuation_entry is never referenced

[Max Ockner]

Hello everyone!

Please review this small fix which removes some dead code from the 
interpreter. TemplateInterpreter::_continuation_entry table and its 
accessor are never called from anywhere else.

Bug: https://bugs.openjdk.java.net/browse/JDK-8169206
Webrev: http://cr.openjdk.java.net/~mockner/8169206.01/

Tested with java -version.

Thanks,
Max
