Define the istate structure.
Move the identity-mapping handler to assembly.

Context again. It turns out, according to SCD 2.4, that registers that didn't have to be saved were saved (%o1 - %o5) and
registers that had to be saved were not saved (%i0 - %i5, %l0 - %l7).

The context_save/context_restore needed two other improvements.
