[SelectionDAG] Correctly Mark Required Analyses (#147649)

#147560 changed when the legacy SelectionDAG pass needs
TargetTransformInfoWrapperPass to always require it (rather than only
when assertions are enabled). `SelectionDAGISelLegacy::getAnalysisUsage`
was not updated in that PR, which was causing crashes on
assertions-disabled builds, which are hard to track down.

This makes the required update, which should avoid crashes being seen on
some buildbots and by some users.
