reland: [DAG] Fix PR45049: LegalizeTypes crash
Sometimes LegalizeTypes knows about common subexpressions before SelectionDAG

Differential Revision: https://reviews.llvm.org/D76994

Reverted in 3ce77142a6452d76d6f97c9a6c2da193e78841ba because the previous patch
broke the expensive-checks bots. The new patch removes the broken check.
