Subject: Add a new attribute called 'jumptable' that creates jump-instruction
 tables for functions marked with this attribute. It includes a pass that
 rewrites all indirect calls to jumptable functions to pass through these
 tables.

This also adds backend support for generating the jump-instruction tables on ARM and X86.
Note that since the jumptable attribute creates a second function pointer for a
function, any function marked with jumptable must also be marked with unnamed_addr.
