Description

We don't use this dialect. The removal triggered the removel of one test:

  • test/Quake/ccnot.qke

The test was not testing anything useful, only kernel inlining, which is already covered in other tests. Furthermore, the test is misleading because, contrary to what the kernel name might indicate, it is not implementing a ccnot.

We don't use this dialect and its presence is a historical artifact.
This change triggered the removal of two tests:

* `test/Quake/ghz.qke`
* `test/Quake/iqft.qke`

Both tests are a reminder of a past when we had to write quantum kernels
directly in MLIR because of a lack of frontend. Both no longer test
aything useful.

The commit modifies `test/Quake/canonical-2.qke`, which was only testing
the canonicalization of `cc.scope` operations. The new form is removes
the clutter, making the test more precise.

`test/Translate/ghz.qke` had to be modified because it uses MLIR's
`affined.for` and its conversion to LLVMDialect requires `scf.for`.
