[Tarantool-patches] [PATCH v4 luajit 1/2] cmake: run tests with Valgrind

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

From: Maksim Tiushev <mandesero@gmail.com>

This patch enables running tests with Valgrind. There is a
`VALGRIND_OPTS` variable [1] that we can set -- it makes the usage of
valgrind more flexible -- we can define any necessary flags in
the command line (not at the building stage). By default, the
suppression file is set to `src/lj.supp`.

Also, this patch disables the following tests when running with Valgrind
due to failures:

Disabled due tarantool/tarantool#10803:
  - tarantool-tests/gh-7264-add-proto-trace-sysprof-default.test.lua
  - tarantool-tests/lj-512-profiler-hook-finalizers.test.lua
  - tarantool-tests/lj-726-profile-flush-close.test.lua
  - tarantool-tests/misclib-sysprof-lapi.test.lua
  - tarantool-tests/profilers/gh-5688-tool-cli-flag.test.lua

Timed out due to running under Valgrind:
  - tarantool-tests/gh-7745-oom-on-trace.test.lua
  - tarantool-tests/lj-1034-tabov-error-frame.test.lua
  - tarantool-c-tests/gh-8594-sysprof-ffunc-crash.c_test

Part of tarantool/tarantool#3705
