Pyqir

Generator now supports LLVM instructions for integer arithmetic and branching. Built-in support for dynamic qubit and result allocation has been removed, but the functionality is still possible using the external functions feature (see the [dynamic allocation example](https://github.com/qir-alliance/pyqir/blob/main/examples/generator/dynamic_allocation.py)).

Breaking Changes

PR [106](https://github.com/qir-alliance/pyqir/pull/106) changes the default way `Result`s are emitted in emitted QIR.

The previous approach used `call %Result* __quantum__qis__m__body(%Qubit* null)` for measurement saving to a `Result` variable. Along with this, branching used `__quantum__rt__result_equal(%Result*, %Result*)` along with `__quantum__rt__result_get_zero` and `__quantum__rt__result_get_one`
to perform branching.

The new default usage in `0.4.0a1` uses static `Result` identifiers instead of dynamic `Result` values. With that, measurement now uses `"call void __quantum__qis__mz__body(%Qubit*, %Result*)` which accepts the static `Result` identifier. As a result, the `pyqir-evaluator` can now see which `Result` is being written to. Branching has also changed to use `call i1 __quantum__qir__read_result(%Result*)` which returns the boolean value of the `Result`.

For the `pyqir-generator`, the use of static and dynamic `Qubit` and `Result` can now be
configured via two new methods on the `SimpleModule` class:

- `use_static_qubit_alloc(bool)`
- `use_static_result_alloc(bool)`
