-    Detensoring is the process through which a tensor value is converted to one
-    or potentially more primitive value(s). During this process, operations with
-    such detensored operands are also converted to an equivalent form that works
-    on primitives.
-
-    The detensoring process is driven by linalg-on-tensor ops. In particular, a
-    linalg-on-tensor op is checked to see whether *all* its operands can be
-    detensored. If so, those operands are converted to their primitive
-    counterparts and the linalg op is replaced by an equivalent op that takes
-    those new primitive values as operands. Therefore, detensoring an op can be
-    divided into 2 main logical phases:
-
-    1. Detect/match an op that can be detensored.
-    2. Detensor the operands of the op and replace it with a primitive
-       equivalent.
-
-    In addition to detensoring individual ops, this pass detensors internal
-    control flow inside a function. All blocks except for the entry block are
-    detensored by converting their arguments whenever possible.
-
-    This can be run on any FunctionOpInterface op and must not be
-    run on others. This is because it performs specific legalization of the
-    blocks that make up the body, which it assumes has is a FunctionOpInterface.
