Teach SimplifyCFG how to simplify indirectbr instructions.
...
- Eliminate redundant successors.
- Convert an indirectbr with one successor into a direct branch.
Also, generalize SimplifyCFG to be able to be run on a function entry block.
It knows quite a few simplifications which are applicable to the entry
block, and it only needs a few checks to avoid trouble with the entry block.

"bonus" instruction to be speculatively executed. Add a heuristic to

instruction only uses values that were already guaranteed to be available.
