Optional jump table support

eBPF for Windows requires support for updating the address of helper functions (when the module hosting them is reloaded).
This is currently implemented as a jump table in eBPF-for-Windows, but the performance is sub-part. A better solution would be to modify uBPF to emit rip indirect calling like this, with the jump table being embedded in the emitted machine code.
call QWORD PTR [rip+0x2023] # 0x2029This might also eliminate the need to perform retpoline based calling.
