Handle all types of errors during trace stitching.

Thanks to Sergey Kaplun and Peter Cawley.

(cherry picked from commit d06beb048)

This commit is a follow-up for the commit
1b8216023 ("Throw any errors before stack
changes in trace stitching."). The patch prepends failures for the
specific error to be thrown. Nevertheless, the error may be thrown due
to retrying trace recording in the case when table bump optimization
is enabled or when OOM is observed during reallocation of the snapshot
or IR buffers.

This patch adds the corresponding protected frame and rethrows the error
after a fixup of the stack.

This patch also tests the correctness of copying the error message to
the top of the stack to get a valid "abort" reason in the `jit.dump`
utility.

Sergey Kaplun:
* added the description and the test for the problem
