Wouter van Oortmerssen e5f4783f98 [WebAssembly] Added basic support for if/else/end_if in MC layer.
Summary:
These instructions are currently unused in our backend, but for
completeness it is good to support them, so they can be used with
the assembler in hand-written code.

Tests are very basic, signature support missing much like other blocks.
