Topic: wasmtime / PR #11851 Disallow fewer instructions in Wizer

alexcrichton opened PR #11851 from alexcrichton:wizer-more-instructions to bytecodealliance:main:

Specifically allow table.get, ref.null, ref.is_null, select (typed), ref.func, and table.size. These are fine to execute and the incompatibility with Wizer instead comes when a table or a reference type global is mutated. That mutation is disallowed elsewhere, however, so there's no need to reject these instructions.
