[PATCH] D68507: [PATCH 24/38] [noalias] ScopedNoAliasAA: use C99 restrict rules for deducing noalias

This is part of the series started by D68484 <https://reviews.llvm.org/D68484>.

Look at {p.addr, p.objId, p.scope} for deducing noalias, making use
of recursive calls to AA to proof that p.addr is not aliasing.

Note: with the legacy pass manager, I succeeded in registering the Alias Analysis manager to the ScopedNoAliasAAPass.
I was not able to get the same effect with the new pass manager. Any help is welcome !

Note: this is a stable point and tests should run fine with the patches applied up to this point.
