[flang-commits] [flang] [mlir] [mlir] Do not merge blocks during canonicalization by default (PR #95057)

This makes sense to me. The aggressive configuration could get a param later (if needed) but almost feels like it could be a separate pass too. Not a blocker here though.

This enables the current state while also allowing folks (probably majority but we'll probably only find out in post if I'm wrong :-)) to avoid the cost.
