[PATCH] Rename variables in gc_relocate related functions to follow LLVM's naming conventions.

[Sanjoy Das]

LGTM given that this is a renaming-only change.

Do you want me to check this in for you?

Another potential cleanup here -- `CreateCall3` returns a `CallInst` so you can just do

```
Callinst *Reloc = ... CreateCall3
```

and elide of the `cast<>`s.

If you do this, please do that in a separate change.
