[php-src] Issue #7771: Incorrect file/line blamed for errors caused by `new SomeClass`

Issue: https://github.com/php/php-src/issues/7771 Comment Author: iluuu1994 I created a small POC here. https://github.com/php/php-src/compare/master...iluuu1994:gh-7771?expand=1 The approach in the PR is to simply replace filename/lineno in the exception, similar to ErrorException. Since there are tons paths for throwing errors in constant expressions I avoided passing the name/lineno by storing it in the execution globals. Unfortunately the lineno in the AST somewhere. I'm still trying to figure out why. Let me know if this approach is ok before I spend too much time on this.
