[Tarantool-patches] [PATCH luajit 0/1] ASAN & LuaJIT allocator

[mandesero at gmail.com]

From: Maksim Tiushev <mandesero at gmail.com>

This patch introduces ASAN instrumentation for the internal LuaJIT allocator.
Each CI job testing with ASAN now includes two scenarios: testing with the
internal LuaJIT allocator and testing with `sysmalloc`. Additionally, certain
tests can be disabled using the `LJ_ASAN_HARDENING` environment variable which
is useful in cases where a test fails due to time constraints.

The ASAN instrumentation of the internal LuaJIT allocator enhances the ability
to detect memory handling errors, particularly when utilizing FFI.
