Hans Wennborg 9311589e8d simplifycfg: Fix integer overflow converting switch into icmp. 
If a switch instruction has a case for every possible value of its type,
with the same successor, SimplifyCFG would replace it with an icmp ult,
but the computation of the bound overflows in that case, which inverts
the test.

Patch by Jed Davis!
