4575c053 - [mlir][scf] fix loop specialization crash when an scf.for result is used (#236046)

[mlir][scf] fix loop specialization crash when an scf.for result is used (#236046) the replacement `scf.if` now has the original loop result types, if the condition is satisfied (i.e bound equal to constant) the then branch replaces the upper bound of the cloned loop with the constant, else the original operation with bound is cloned as such. the yield op is created inside both the branches if there is any resullt, the original op's result users are redirected to the `scf.if` results and the original loop is erased. fixes #235552 assisted by: claude
