Most control structures in WebAssembly do not have a clear execution
semantics, they are more like markers. Hence the execute state, and the
change in the state, when breaking on them and stepping over them is
unclear.
Hence this CL just makes them non-breakable. If the user tries to set a
breakpoint on them, this breakpoint will automatically be propagated to
the first instruction after the respective control opcode (this is
tested for other cases in existing tests).
