[RuntimeDyld, PowerPC] Fix relocation detection overflow
Code in RuntimeDyldELF currently uses 32-bit temporaries to detect
whether a PPC64 relocation target is out of range. This is incorrect,
and can mis-detect overflow where the distance between relocation site
and target is close to a multiple of 4GB. Fixed by using 64-bit
temporaries.
Noticed while debugging PR32650.
