Merge previous PR and rebase pls. These are too many files to review 😅

Sure thing! Let me just finish up #126. |
- Add ArgumentMismatchError - Check argument count and types of aliases - Add not found error for aliases as well - Add locations to LJErrors after catching them in the places they don't include positions
- Validate ghost invocations instead of relying on Z3 output - Throw LJErrors in AST expressions

Could we provide the hints in here instead of creating an error with the first candidate? Like "gh(int) not found. Maybe you meant gh(double), gh(int, double)"
Similar to what you did on the warning for external method not found

Definitely! I'll do that in another PR with more cases.

this method is too long. check the suggestions i left, it might improve. If not, we might need to split this into smaller bits

This PR fixes the problem mentioned in #126, where we were getting a not found error instead of an argument mismatch error on wrong alias invocations, because we were not validating them beforehand. Also, we were previously relying on the Z3 output to get ghost invocation errors. Instead, we now also validate ghost calls before sending them to the SMT solver. For both ghosts and aliases, in either wrong argument count or types, the
ArgumentMismatchErrorwas introduced.
