fix PR4848 an infinite loop when indexing down through a recursive gep
and we get the original pointer type. This doesn't mean that we're
at the first pointer being indexed. Correct the predicate.

Fix a bug in the over-index constant folding. When over-indexing an2009-08-19T22:46:59ZDan Gohmangohman@apple.com2009-08-19T22:46:59Zurn:sha1:3d01334e6fa5caba1361d088fabf728c64b23c58

inside that struct, such that attempting to find further getelementptr
indices will fail. In such cases, folding cannot be done.

appear to depend on the initializer value.

other passes to be more conservative. This canonicalization also
allows the constant folder to add "inbounds" to GEPs.
