When enabling any coverage mode (other than best-effort), we trigger deoptimization of all functions on the heap. Prior to the recent removal of the weak list of optimized functions [0], we'd unlink optimized code from all relevant JSFunctions during the call to DeoptimizeAll. After the weak-list-removal, this was no longer the case, hence this [1] change which attempts to reset the code object from the SharedFunctionInfo for all found JSFunction objects. But this can create a situation in which JSFunctions are set up incorrectly s.t. they have unoptimized code but no feedback vector. This CL fixes that by leaving JSFunction objects untouched and relying on self-healing mechanisms (CompileLazyDeoptimizedCode) to fix up JSFunction::code.

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.

Control Flow Integrity [1] indirect call checking is a compiler- instrumentation that verifies that function pointers are only used to call functions whose type signatures matches the type of the function pointer. The once implementation casts function pointers to different types--refactor it to pass around a std::function that calls the provided function pointer with its original type instead.
