8258653: CallJavaNode::_bci is not in use

[navyxliu]

The member variable CallJavaNode::_bci is completely dead in release build.
In debug builds, CallJavaNode::validate_symbolic_info does refer to it, but
the information can obtain from jvms()->bci(). CallJavaNode also copies _bci
to MachCallJavaNode, but CodeGen doesn't use it as well.
