Implement a poor man's jump table.

We will eventually support real jump tables, but for now just expand
br_table into a sequence of conditional branches.

Add trap codes to the Cretonne IL.
...
The trap and trapz/trapnz instructions now take a trap code immediate
operand which indicates the reason for trapping.

Don't require that the fallthrough instruction has an encoding.
...
A fallthrough jump is actually represented as 0 bytes, so no encoding is
needed.
Also allow for unencoded instructions in the generated emit_inst
implementations. The verifier has stricter rules for when this is
allowed.
