Pull from master repo:
Put the genswitch() code that is found in most backends into
the MI part. The backend version is renamed to mygenswitch()
and can provide improved translations for switch statements.
Improved implementation of the switch constraints/semantics
described in the standard.

With help and comments from ragge and gmcgarry
