Add EG(bailout) consistency assertion

[iluuu1994]

Make sure EG(bailout) is what we expect in zend_end_try(). This will detect faulty jumps into or out of zend_try blocks, as in 38628e8.

This can be merged only after #21666.

This uncovered faulty code in zend_jit_trace(), which should likely be backported.

I needed to tweak slightly, because when we hit zend_catch we're already re-setting the EG(bailout). I think we can check at the end of the try block, and the start of catch.
