Avoid throw expression leaks

Mark "throw" used in expression context with a flag, and don't
treat it as a BB terminator in that case. This prevents us from
optimizing away the following opcodes as unreachable, which may
result in live ranges being dropped incorrectly.

Close GH-5450.

Make throw statement an expression

RFC: https://wiki.php.net/rfc/throw_expression

This has an open issue with temporaries that are live at the time
of the throw being leaked. Landing this now for easier testing and
will revert if we cannot resolve the issue.

Closes GH-5279.
