[upstream-update] update AA interface usage

SVN r262490 reformulated the Alias Analysis interfaces.  The TLI is no longer
needed to construct the AA Result.  Because the TLI was used specifically for
the base constructor, we now no longer need that option.  Simplify it according
to the new API.  NFC.
