Description
G1RemSet::oops_into_collection_set_do performs three different phases at once:

Update remembered set
Scan (Java heap) remembered set
Code root scan

however, everything is kicked off by only calling this method. This has the disadvantage that we can not use these phases separately (for one reason or another), also because each of these phases does timing by itself.

For example, JDK-8153503 fails because of this.

Break up oops_into_collection_set_do() into its components to facilitate reuse.
Comments
Made obsolete/fixed by the cleanup in JDK-8218668.
