br_table optimizations (#1502)
Inspired by #1501
* remove unneeded appearances of the default switch target (at the front or back of the list of targets)
* optimize a switch with 0, 1 or 2 targets into an if or if-chain
* optimize a br_if br pair when they have the same target
Makes e.g. fastcomp libc++ 2% smaller. Noticeable improvements on other things like box2d etc.
