Jinsong Ji 4cae41ddbe [DAGCombine] Check reassoc flags in aggressive fsub fusion 
The is from discussion in https://reviews.llvm.org/D104247#inline-993387

The contract and reassoc flags shouldn't imply each other .

All the aggressive fsub fusion reassociate operations,
we should guard them with reassoc flag check.
