The existing implementation causes unnecessary heap allocations for javascript syscalls: Call, Invoke, and New. The new change seeks to hint the Go compiler to allocate arg slices with length <=16 to the stack. Original Work: CL 367045 - Calling a JavaScript function with 16 arguments or fewer will not induce two additional heap allocations, at least with the current Go compiler. - Using syscall/js features with slices and strings of statically-known length will not cause them to be escaped to the heap, at least with the current Go compiler. - The reduction in allocations has the additional benefit that the garbage collector runs less often, blocking WebAssembly's one and only thread less often.
