There were over 150 places in *::Notify() functions that did some dynamic_cast<SfxSimpleHint*> of which ~98% were unnecessary because the base class SfxHint passed was an SfxSimpleHint anyway. dynamic_cast operations come with quite some cost, so avoid if possible. Specifically for ScFormulaCell::Notify() that created a bottleneck in scenarios where cells were notified that already handled a previous notification. In mass operations doing the dynamic_cast before it could be decided whether having to act on it or not this made 2/3 of all time spent in the Notify() call. To get rid of that rename/move SfxSimpleHint to SfxHint and let classes derive from SfxHint instead of SfxSimpleHint. This comes only with a slight cost that an additional sal_uInt32 is transported in such hints, initialized to 0, but this is neglectable compared to the huge gain. For the rare cases where a Notify() actually expects both, an SfxHint (formerly SfxSimpleHint) and a derived hint, this changed order of the dynamic_cast involved so the simple SfxHint::GetId() is handled last. Modules using such combinations can further optimize by treating the simple SfxHint::GetId() first once verified that none of the other derived hints use an ID not equal to zero respectively none of the ID values the simple hint uses.
