Subject: [PATCH] mruby-compiler: remove traditional word/symbol array codegen
 paths

Remove unused codegen_words and codegen_symbols functions along with their
corresponding cases in the main codegen switch. These became dead code
after converting new_words and new_symbols to always use variable-sized nodes.

Also remove var_nodes_enabled conditions from new_words and new_symbols,
completing the transition to always using variable-sized nodes for word and
symbol arrays.
