Do TseTse checks with typechecker later

The typechecker is known to be slow to create due to https://github.com/Microsoft/TypeScript/issues/27997

By moving the non-typechecker checks earlier in the process, I was able to observe significant savings in the `perfTrace.wrap` total times:
- `CheckReturnValueRule`: 1,036ms, down from 2,102ms
- `MustUsePromisesRule`: 119ms, down from 1,174ms

Closes #359
