[PATCH] D26594: IR: Change the gep_type_iterator API to avoid always exposing the "current" type.

[Peter Collingbourne via llvm-commits]

pcc created this revision.
pcc added a reviewer: dblaikie.
pcc added a subscriber: llvm-commits.
Herald added subscribers: eraman, nemanjai, mzolotukhin, jfb.

Instead, expose whether the current type is an array or a struct, if an array
what the upper bound is, and if a struct the struct type itself. This is
in preparation for a later change which will make PointerType derive from
Type rather than SequentialType.
