Pull Request Overview
This PR fixes a bug in the interpreter's call handling where tailcall flags were incorrectly applied to non-marshaled pinvoke calls. The fix suppresses the tailcall optimization when the target is a non-marshaled pinvoke, which resolves a specific regression test failure.
- Adds conditional logic to disable tailcall for non-marshaled pinvoke targets
- Removes an assertion that was preventing the code from handling this case properly
