RFR (S) 8158397: Crash: assert(save_resolved_method == resolved_method()) failed: does this change?

[Coleen Phillimore]

Summary: remove assert.  it does change.

I'd left some debugging code from a prior change.

open webrev at http://cr.openjdk.java.net/~coleenp/8158397.01/webrev
bug link https://bugs.openjdk.java.net/browse/JDK-8158397

Tested and verified with failing testcase, defmeth tests and selection 
resolution tests.

Thanks,
Coleen
