core: Introduce accessors for current per_cpu fields

Reserve a register for a quick lookup of fields in the current per_cpu
data structure and enable the address, cpu_id and cell for such direct
access. The accessors are named this_<field>().

This will allow us to avoid passing context references around to deeply
nested users.
