Speculatively revert r108813, in an attempt to get the self-host buildbots working again. I don't see why this patch
...
would cause them to fail the way they are, but none of the other intervening patches seem likely either.

Rework scev-aa's basic computation so that it doesn't depend
...
on ScalarEvolution successfully folding and preserving
range information for both A-B and B-A. Now, if it gets
either one, it's sufficient.

There are two ways of checking for a given type, for example isa<PointerType>(T)
...
and T->isPointerTy(). Convert most instances of the first form to the second form.
Requested by Chris.

Chris claims we should never have visibility_hidden inside any .cpp file but
that's still not true even after this commit.

Create a ScalarEvolution-based AliasAnalysis implementation.
...
This is a simple AliasAnalysis implementation which works by making
ScalarEvolution queries. ScalarEvolution has a more complete understanding
of arithmetic than BasicAA's collection of ad-hoc checks, so it handles
some cases that BasicAA misses, for example p[i] and p[i+1] within the
same iteration of a loop.
This is currently experimental. It may be that the main use for this pass
will be to help find cases where BasicAA can be profitably extended, or
to help in the development of the overall AliasAnalysis infrastructure,
however it's also possible that it could grow up to become a directly
useful pass.
