[Tarantool-patches] [PATCH v5 luajit 0/3] Valgrind testing

[Sergey Kaplun]

Changes in v5:
- Backported patch to fix "uninitalised value" warning during vmevent
  processing of the `IR_NOP`.
- Added the additional suppression file to avoid false positives in
  string comparisons not covered by the original suppression file.
- Remove the `--verbose` flag, since it makes the output too messy.

Changes in v4:
- Replaced the `VALGRIND_OPTIONS` variable with `VALGRIND_OPTS`, which
  is provided by Valgrind.
- Enabled running `tarantool-c-tests` under Valgrind:
  * Disabled the `tarantool-c-tests/gh-8594-sysprof-ffunc-crash.c_test` due
    to timeout.
- Renamed the variable for skipping tests to `LUAJIT_TEST_USE_VALGRIND`
  and setted it via `LUA_TEST_ENV_MORE`.
- Added the `--error-exitcode=1` flag to `VALGRIND_OPTS` in CI for stricter
  error handling.
