[Tarantool-patches] [PATCH luajit 0/2] Disable strcmp optimizations in Valgrind build

[mandesero--- via Tarantool-patches <tarantool-patches@dev.tarantool.org>]

From: mandesero <mandesero@gmail.com>

In this Patchset, the optimization of strcmp is disabled during the LuaJIT build under Valgrind.
The string comparison is done byte-by-byte. Additionally, the memcmp functions, where strings
are compared, have been replaced to disable any potential internal optimizations.

Branch: https://github.com/tarantool/luajit/tree/mandesero/lj-3705-turn-off-strcmp-opt-in-debug
Issue: https://github.com/tarantool/tarantool/issues/3705

Some tests are failing under Valgrind due to the timer profiler (SIGPROF) or upon reaching
the maximum test duration, so they have been disabled.

  c: disable strcmp optimization in Valgrind build
  cmake: running tests under Valgrind, disable tests that failed under
    Valgrind
