Export functions necessary to implement JIT compilers

[DinoV]

There's some internal functionality that needs to be exported to support JIT compilers which are using PEP 523 to hook in. Primiarly there's things around dictionaries which need to be exposed to specialize attribute access. But there's also error reporting functionality that's not exported to match CPython's tracebacks and some random helpers which are used around frames.
