There are several other clean ups I would like to do in this file,
but this can wait until we promote the query.

we have the option to use `regex.getAValueReachingSink`
rather than `regex.asSink`, but it will likely be used as a
sink for data flow.

Before, we would be recursive in all of `MethodCall::getMethodName`:

```
Evaluated named local Synthesis#d9ff06b1::AssignOperationDesugar::SetterAssignOperation::getCallKind#ffff#shared#3@Synthesi in 9803ms on iteration 14 (size: 31006941).
Evaluated relational algebra for predicate Synthesis#d9ff06b1::AssignOperationDesugar::SetterAssignOperation::getCallKind#ffff#shared#3@Synthesi on iteration 14 running pipeline main with tuple counts:
          256419  ~1%    {2} r1 = SCAN Call#841c84e8::MethodCall::getMethodName#0#dispred#ff#prev_delta OUTPUT In.1, In.0
        31006941  ~8%    {4} r2 = JOIN r1 WITH Synthesis#d9ff06b1::MethodCallKind#ffff#prev ON FIRST 1 OUTPUT Lhs.1, Rhs.1, Rhs.2, Rhs.3
                         return r2
```

Now, we have restricted that to only the relevant method names.
