The previous code assumed that trap handling was a global concept, defined by function trap_handler::UseTrapHandler(). This CL does the first step in changing the decision to be specifiable at a module level. Therefore trap_handler::UseTrapHandler() is replaced by trap_handler::IsTrapHandlerEnabled(), and communicates if compilation supports the use of trap handlers (but still allowing the use of bounds checking on memory accesses). It then refactors the classes ModuleEnv and WasmCompiledModule to have a field "use_trap_handler" that specifies if traps should be used for the memory accesses in the module being compiled.
