This function returns the address of the entry point of the function whose descriptor's address is given.

| bytes | the array of bytes to read the next 8 bytes from. Note that this array must be at least 8 bytes long. |
| result | where to store the resuting uint64_t that was read. |
| is_big_endian | if true, read the 8 bytes in Big Endian mode, otherwise, read them in Little Endian. |
| true | if the 8 bytes could be read, false otherwise. |
