Add write barrier calls for direct marking objects.

Browse source 
This commit adds write barriers for objects marked from `rb_iseq_mark`.
r62851 introduced direct marking from iseqs to:

* keyword arg default values
* catch table iseqs
* VALUEs embedded in encoded instructions

This patch adds missing write barrier calls to those references.
