Handle OOM error on stack resize in coroutine.resume and lua_checkstack.

Thanks to Peter Cawley.

(cherry picked from commit a5d2f70c7)

If the OOM or stack overflow error is obtained during
`lj_state_growstack()` in the `coroutine.resume()` it may raise an error
leading to the incorrect error message and unexpected behaviour for
this corner case. Also, `lua_checkstack()` may raise an OOM error
leading to panic on an unprotected lua_State, for example.

This patch handles these cases by protecting `lj_state_growstack()`.

* added the description and the test for the problem
