As part of this extension this change also does some general cleanup
1) Make all the methods take `RewriterBase` as arguments instead of
creating their own builders that tend to crash when used within
pattern rewrites
2) Split `coalesePerfectlyNestedLoops` into two separate methods, one
for `scf.for` and other for `affine.for`. The templatization didnt
seem to be buying much there.
Also general clean up of tests.
1. parallel-loop-collapsing is renamed to test-scf-parallel-loop-collapsing.
2. The pass adds various checks to provide error messages instead of
hitting assert failures.
3. Testing is added to verify these error messages
This is roughly an NFC. The name changes, but all checked behavior
previously would have resulted in an assertion failure. Almost no new
support is added, so this pass is still limited in scope to testing the
transform behaves correctly with input arguments that perfectly match
the ParallelLoop's iterator arg set. The one new piece of functionality
is that invalid operations will now be skipped with an error messages
instead of producing an assertion failure, so the pass can be used with
expected failures for pieces of the IR not cared about with a specific
RUN command.

The patch introduces the required changes to update the pass declarations and definitions to use the new autogenerated files and allow dropping the old infrastructure.

This aligns the SCF dialect file layout with the majority of the dialects.

This has been a major TODO for a very long time, and is necessary for establishing a proper
dialect-free dependency layering for the Transforms library. Code was moved to effectively
two main locations:
* Affine/
There was quite a bit of affine dialect related code in Transforms/ do to historical reasons
(of a time way into MLIR's past). The following headers were moved to:
Transforms/LoopFusionUtils.h -> Dialect/Affine/LoopFusionUtils.h
Transforms/LoopUtils.h -> Dialect/Affine/LoopUtils.h
Transforms/Utils.h -> Dialect/Affine/Utils.h
The following transforms were also moved:
AffineLoopFusion, AffinePipelineDataTransfer, LoopCoalescing
* SCF/
Only one SCF pass was in Transforms/ (likely accidentally placed here): ParallelLoopCollapsing
The SCF specific utilities in LoopUtils have been moved to SCF/Utils.h
* Misc:
mlir::moveLoopInvariantCode was also moved to LoopLikeInterface.h given
that it is a simple utility defined in terms of LoopLikeOpInterface.
