Remove Value::setName(const char*).
...
- Split into a separate patch because there is a slight functionality change,
it is no longer valid to call setName(0), which was equivalent to
setName(""). I'm hoping no one depends on this...

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.
