Disable null pointer folding transforms for non-generic address spaces. This should probably be a target-specific predicate based on address space. That way for targets where this isn't applicable the predicate can be optimized away.

Change Sema::ActOnCallExpr to construct the CallExpr early and put it into
...
and OwningPtr instead of constructing only after all of sema is done. This
has a couple of effects:
1. it fixes memory leaks from all the error cases in sema
2. it simplifies the code significantly.
The cost of this is that the error case now new's and delete's an expr where
it did not before, but we don't care about the perf of the error case.

Don't break critical edges for single-bb loops, this helps with PR1877, though
...
it is only a partial fix. This change is noise for most programs, but
speeds up Shootout-C++/matrix by 20%, Ptrdist/ks by 24%, smg2000 by 8%,
hexxagon by 9%, bzip2 by 9% (not sure I trust this), ackerman by 13%, etc.
OTOH, it slows down Shootout/fib2 by 40% (I'll update PR1877 with this info).
