Justin Lebar c8a4e60a71 Convert an APInt to int64_t properly in TTI::getGEPCost(). ...

Summary:
If the pointer width is 32 bits and the calculated GEP offset is
negative, we call APInt::getLimitedValue(), which does a
*zero*-extension of the offset.  That's wrong -- we should do an sext.

Fixes a bug introduced in rL314362 and found by Evgeny Astigeevich.
