[Tarantool-patches] [PATCH v4 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()

Changes in v3:
- Cleaned up mess in Makefile.dep
- Fixed naming and comments
- Fixed padding in struct GCState for 64-bit architectures
- Fixed counting amount of JIT traces
- Fixed objects counting at trace recording
- Added counting of colors
- Added C and Lua tests

Changes in v4:
- Removed counting of colors
- Changed global_State structure correspondingly for 32-bit arm build

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