Switch LLVM to use 64-bit offsets (2/5)

[ikudrin]

Summary

This updates all libraries and tools in LLVM Core to use 64-bit offsets which directly or indirectly come to DataExtractor.

[ikudrin]

I know this is huge. Locally, I have 20+ separate patches covering that, but I am not sure if it is simpler to look at one big patch or lots of smaller patches.

[dblaikie]

Looks reasonable to me at a glance - individual changes would be easier to review, but may not be worth separating out.

[jhenderson]

You missed one that got added very recently! See the FIXME introduced in rL367942.

[ikudrin]

Thanks! I'll remove that code in the cleanup patch.
