> `zend_compile_return()` currently leaves `CG(zend_lineno)` at the last line compiled inside a multiline return expression. As a result, `VERIFY_RETURN_TYPE` and `RETURN` are attributed to a match arm or ternary branch instead of the `return` statement. Coverage drivers then omit the actual return line and may report a different branch line as executed. This is the specific return-expression case described in GH-22727 and is part of the broader GH-18985 issue.
>
> This patch captures the statement line before compiling the expression and restores it before emitting return-related opcodes. It deliberately avoids the broader expression compiler changes from GH-22833 that were reverted.
>
> A PHPT regression test verifies the user-visible TypeError line. The test fails on PHP 8.4.24 with line 6 instead of line 5, and passes on the patched PHP 8.4.26-dev build.
>
> Validation: debug NTS build with all `Zend/tests` (4,837 passed, 134 skipped, 1 expected failure, 0 failures); debug ZTS build with the focused regression test; and PCOV 1.0.12 verification showing the direct `return match` line changes from absent to hit count 1.
