370ea51f - [mlir][tosa] Robustify Tosa_IfOp against null dereference and wrong assertion (#159756)

[mlir][tosa] Robustify Tosa_IfOp against null dereference and wrong assertion (#159756) Fixes #159650. The current implementation ICE out if we access an IfOp's terminator when it doesn't have it. Instead the PR defers the job of verifying that a block would have at least a terminator. The current implementation also crashes with cast<YieldOp> if the terminator is not a YieldOp, the PR also defers the job of verification to the op itself.
