ShortForm: fix LuaJIT's error with large blocksets
ShortForm: fix LuaJIT's error with large blocksets

When a short form was being loaded with LuaJIT, the following
error message occurred:

main function has more than 65536 constants

To fix this error, I changed generated code so that each block
is added in separate function.
