[Tarantool-patches] [PATCH v2 0/2] Implement LuaJIT platform metrics

[Sergey Kaplun]

The series consists of 2 patches. The first one adds corresponding
counters to LuaJIT internal structures. The second provides C and Lua
API using this counters to collect metrics.

Branch: https://github.com/tarantool/luajit/tree/skaplun/gh-5187-luajit-metrics
Issue: https://github.com/tarantool/tarantool/issues/5187

Changes in v2:
- Fixed naming and comments
- Fixed padding in struct GCState
- Dropped unnecessary initialisations inside lua_newstate()
- Avoided flushing any of metrics after each call of luaM_metrics()

Sergey Kaplun (2):
  core: introduce various platform metrics
  metrics: add C and Lua API
