Fix the last -Wnon-pod-memset I'm seeing. This is benign, but appears
a bit more sinister as the memset doesn't do what the constructor does.
There seems to be a cleaner solution than a cast here though, instead we
can point the memset destination into the union its actually trying to
clear.
An alternative is to point to the Untyped member of this union. Review
appreciated, and if that is cleaner I'm happy to switch. All of these
should be functionally equivalent to the original code.

make a couple of changes to the standard pass pipeline:
1. Only run the early (in the module pass pipe) instcombine/simplifycfg
if the "unit at a time" passes they are cleaning up after runs.
2. Move the "clean up after the unroller" pass to the very end of the
function-level pass pipeline. Loop unroll uses instsimplify now,
so it doesn't create a ton of trash. Moving instcombine later allows
it to clean up after opportunities are exposed by GVN, DSE, etc.

Add support for switch and indirectbr edges. This works by densely numbering
all blocks which have such terminators, and then separately numbering the
possible successors. The predecessors write down a number, the successor knows
its own number (as a ConstantInt) and sends that and the pointer to the number
the predecessor wrote down to the runtime, who looks up the counter in a
per-function table.
