middle-end/111591 - explain why TBAA doesn't need adjustment
While tidying the prototype patch I've done for the reduced testcase
in PR111591 and in that process trying to produce a testcase that
is miscompiled by stack slot coalescing and the TBAA info that
remains un-altered I've realized we do not need to adjust TBAA info.
The following documents this in the place we adjust points-to info
which we do need to adjust.
PR middle-end/111591
* cfgexpand.cc (update_alias_info_with_stack_vars): Document
why not adjusting TBAA info on accesses is OK.
