[PATCH] D34409: Use 64bit jump table with large code model on 64bit

PPC changes reverted and tests updated. I believe this addresses all the comment so far.

So to summarize,

On PPC64, there's some magic that fixes the large offset so the final code is correct already.
On AArch64, there might be something fancy we can do (use the pointer that we use to find the data section?) but this should make it work correctly before that.
On X86-64, this is needed to make it behave correctly. Not sure if there's better trick.
