add stop-after stage for semantic analysis about solidity HOT 4 OPEN

Hey @0xalpharush! Thanks for reporting this. I have a few comments.

The compiler will currently stop after analysis in the case where no options are being requested that could trigger compilation. Devs were running into a bug wherein unnecessary compilation was being performed when --via-ir was used. This was recently fixed (see: #14917 and the corresponding fix in #14926).

Please note that the current behaviour solves your issue unless you have observed any other options (such as the --via-ir in the previous bug) that might be triggering compilation unnecessarily. If so, please mention those as a response to this. It would make most sense to work on a fix for that which would solve the underlying issue.

On the flip side, if you were already aware of the above and have a specific use case in mind that is not possible to implement with the current state of the compiler, feel free to outline it for us.

I don't see how that issue or PR is related to the --stop-after flag or the limitations of the parsing stage that motivated my feature request. I don't think this is a bug or something that can be worked around as it is not implemented

EDIT: I think I misunderstood and you're suggesting to simply not request --bin and it should speed up everything else. Did you mean that solc --ast or solc --ast --via-ir should produce a complete AST with reference ids and imports resolved or am I mistaken?

You understand it correctly. :)

So my ask here is for you to mention any possible cases that aren't covered by the current behaviour. In which case, it would make sense to keep this issue open. If not, I would close this issue for now.
