[WebAssemby] Implement block signatures.
Per spec changes, this implements block signatures, and adds just enough logic to produce correct block signatures at the ends of functions. Differential Revision: https://reviews.llvm.org/D25144 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@283503 91177308-0d34-0410-b5e6-96231b3b80d8
