8000821: JSR 292: C1 fails to call virtual method (JRUBY-6920)
Reviewed-by:

GraphBuilder::try_method_handle_inline calls GraphBuilder::try_inline
to inline the target of method handle calls.  But try_inline doesn't
do CHA; GraphBuilder::invoke does that.

The easy fix for now without refactoring the whole logic in C1 (which
is not trivial, I tried) is to only inline static and statically
bindable methods for method handle calls.  This shouldn't affect
performance since most methods are statically bindable and C2 doesn't
have this problem.
