This change avoids the panic in early returns by blocking them in RCA and providing the user with compile-time feedback before failing during QIR generation. It also includes updates to partial evaluation to ensure that the panicking case is now treated as a unimplemented graceful failure, since we don't have proper support for it. Since QIR generation for programs with early return have never properly been handled, this doesn't take any functionality away but rather ensures earlier indication of the unsupported patterns at compile time. I filed #2387 to cover the additional work needed to fully support dynamic explicit returns. Fixes #2290
