Is there any branch that fully supports Lua 5.3 syntax?

[François Perrad]

if you speak about the new operators introduced by Lua 5.3:

• the branch op53_sugar is bugged, see LuaJIT#317
• the branch op53 (used by LuaJIT#312) is incomplete (only x86), out dated but it is the better starting point for some experiments.

But Lua 5.3 also introduces a distinction between integer and float, and previously Lua 5.2 introduces _ENV; there is nothing for that.

LuaJIT's dual number build option does kind of give you an integer type but its mostly just behind the scenes .
