Title: Supress using switches with fallthru or a empty default label.

On some coding standards like MISRA-C, they don't permit fallthru in switch clauses without comments.
And they requires default labels always even if there is nothing to do.

I think their rules are not best practices. But also they are not bad know-hows.
In practical, we are hard to ignore their guideline rules if we use mruby in embedded systems.

This patch is to modify using if-else. This will be MISRA-C acceptable.
