Adjust filename/lineno for constant expressions

[iluuu1994]

Closes GH-7771

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. Let me know if this approach is ok before I spend too much time on this.

Is there a particular reason, why you chose to explicitly provide an exception specific lineno, instead of feeding it into zend_get_executed_lineno and the file equivalents? (which exceptions read from)

[iluuu1994]

@bwoebi What you're suggesting is returning EG(exception_filename)/EG(exception_lineno) from zend_get_executed_filename/zend_get_executed_lineno if they are set? No particular reason, I can adjust it.

[bwoebi]

essentially yes, just a more appropriate name, like EG(filename_override) EG(lineno_override) or such.

Looks good to me :-)
