Revert the addition of hasNoPointerOverflow to GEPOperator.
...
Getelementptrs that are defined to wrap are virtually useless to
optimization, and getelementptrs that are undefined on any kind
of overflow are too restrictive -- it's difficult to ensure that
all intermediate addresses are within bounds. I'm going to take
a different approach.
Remove a few optimizations that depended on this flag.

Add plumbing for the `linker_private' linkage type. This type is meant for

this. I'm not sure if that includes anyone subscribed to llvm-commits,
