Andy Wingo 35cd7fac8b Fix jmp-shortening on x64 when target within instruction. 
* lightening/x86.c (jit_try_shorten): If the address is within the
  last instruction, don't shorten.  If the intstruction is a jump, we
  could elide it entirely in some cases, but we don't know if the user
  captured the PC before calling jit_patch_here.  Better to leave this
  to the user.

Thanks to Helmut Eller for the bug report and test case in
https://gitlab.com/wingo/lightening/-/issues/17.
