This reverts commit c6b153fd.

Reason for revert: Doesn't compile on the tree.

Original change's description:
> [cctest] Add fuzz tests for generating parallel moves.
> 
> These new tests are somewhat similar to the existing gap resolver tests except
> we use the code generator and eventually run the generated code. The main idea
> is to cover cases that are difficult to hit, such as move from/to slots which
> are out of range of loads and stores, but may happen nonetheless.
> 
> At this time, the tests only make sure the code generator actually generated
> some code, and that this code runs. In the future, it would be great to also
> check that the moves were actually performed.
> 
> Bug: v8:6553
