Hi all,

While working on JDK-8165949 [0] I realized that gen_process_roots 
needed to be cleaned/split up to allow it to be fixed. This work had in 
big parts already been done as part of an enhancement [1] that never got 
pushed. That enhancement included another cleanup as well but I have 
split it out to only include the necessary part in this fix. It splits 
gen_process_roots into two different versions, one used for young 
collections and one for old. This make the two methods much easier to 
follow and removes some special cases. I will post a second review for 
the actual bug-fix.
