Custom lua instruction format

[Baozeng <sploving1@...>]

Hi all, 

As we know, Lua instruction format is the opcode with 6 bits,  `A` with 8 bits, `B` and `C` with 9 bits (together 32 bits)

I custom opcode with 8 bits, `A` with 8 bits,  `B` and `C` with 8 bits.  and use the lua test-suite (https://www.lua.org/tests/) to test it and It have passed all the test.    I want to know does it  affect user's program? 

I only know that with 8 bits for `B` and `C`, the max jump offset is shorter than before. will it affect the normal user? Thank you.
