Subject: [PATCH 2/5] Revert "[mlir][tosa] Align `shift` attribute of
`TOSA_MulOp` with the spec (#67816)"
This reverts commit 363c617aac9d5e8058be549a3c59e3b085c09a54.
Temporarily reverting TOSA asm format change to let integrations catch up.

Subject: [PATCH 3/5] [mlir][affine] ValueBoundsConstraintSet: Fully compose
affine.apply (#68899)
Fully compose `affine.apply` ops before adding them to the underlying
`FlatLinearConstraints`. This works around a limitation of
`FlatLinearConstraints`, which cannot deduce a constant bound if it
involves two identical local variables.
Details for future improvements of `FlatLinearConstraints`: The
constraint set infrastructure fails to compute a constant bound of -8
for the first variable.

Recent changes (https://github.com/llvm/llvm-project/pull/66930)
disabled vector transfer ops hoisting with view-like intermediate ops.
The recommended way is to fold subview ops into transfer op indices
before invoking hoisting. That would mean now we see transfer op indices
involving dynamic values, instead of static constant values before with
subview ops. Therefore hoisting won't kick in anymore. This breaks
downstream users.
To fix it, this commit enables hoisting transfer ops with dynamic
indices by using `ValueBoundsConstraintSet` to prove ranges are disjoint
in `isDisjointTransferIndices`. Given that utility is used in many
places including op folders, right now we introduce a flag to it and
only set as true for "heavy" transforms in hoisting and load-store
forwarding.

Subject: [PATCH 5/5] [mlir][TilingInterface] Add `scf::tileUsingSCFForallOp`
method to tile using the interface to generate `scf::forall`.
Similar to `scf::tileUsingSCFForOp` that is a method that tiles
operations that implement the `TilingInterface`, using `scf.for`
operations, this method introduces tiling of operations using
`scf.forall`. Most of this implementation is derived from
`linalg::tileToForallOp` method. Eventually that method will either be
deprecated or moved to use the method introduced here.
