s390x: Migrate branches and traps to ISLE

Browse Source 
In order to migrate branches to ISLE, we define a second entry
point `lower_branch` which gets the list of branch targets as
additional argument.

This requires a small change to `lower_common`: the `isle_lower`
callback argument is changed from a function pointer to a closure.
This allows passing the extra argument via a closure.

Traps make use of the recently added facility to emit safepoints
from ISLE, but are otherwise straightforward.
