This PR adds an initial fuzzer for testing LSQ elision in Dynamatic. It uses a type system that is specifically designed to not require any memory ordering.

The logic currently used is very simple: Only a single Write-after-Read statement is generated and the write operation is either data- or control dependent on the read operation. Support for more complicated constructs will be added in future PRs. For now this fuzzer already finds suboptimal code in milliseconds.

Depends on #837
