Heejin Ahn 3648370a79 [WebAssembly] Fix a non-determinism problem in FixIrreducibleControlFlow ...

Summary:
We already sorted the blocks when fixing up a set of mutual
loop entries, however, there can be multiple sets of such
mutual loop entries, and the order we encounter them
should not be random, so sort them too.
