  Log Message:
  -----------
  [XRay] Change Sled.Function to PC-relative for sled version 2 and make llvm-xray support sled version 2 addresses

Follow-up of D78082 and D78590.

Otherwise, because xray_instr_map is now read-only, the absolute
relocation used for Sled.Function will cause a text relocation.
