The helper function storePlainArg in handler and jit_compiler reinterpret-casts pointers to memory in vectors of char in order to store arguments in them. However, this violates strict aliasing and is unnecessary as the resulting pointers are immediately converted to void* after all calls to the function. As such, this patch simplfies these implementations to always return void* and use memcpy to avoid the alias violation.
