[patch] [efficiency] Move getAliasSetForPointer under if (!IgnoreAliasing)

[Dmitry N. Mikushin]

Dear Polly Team,

Attached patch should make a small contribution to Polly passes efficiency,
which seems to become in focus.

Synopsis: there is no need to get the AliasSet for pointer, if aliasing is
ignored (true for KernelGen).

Thanks,
- D.
