Re (b) – yes, 5.4's VM introduces a generational garbage collector and special-case instructions for numeric types which consistently improve performance, at least even in the general-purpose programs that I run (gamedev and the VM as a compilation target.)
That being said, I use Lua on an architecture that LuaJIT doesn't support anyway – 68k.
