Feature #10328: [PATCH] make OPT_SUPPORT_JOKE a proper VM option

----------------------------------------
This is not a joke :)

I worry about executable size with things like [Feature #10326],
and I noticed unused instructions are emitted even with jokes disabled

This reduces executable size slightly on x86-64-linux:

   text	| data  |   bss  |    dec  |   hex  | filename
--------+-------+--------+---------+--------+------------
2782156 | 22400 |  71880 | 2876436 | 2be414 | ruby.before
2781420 | 22400 |  71880 | 2875700 | 2be134 | ruby.after

Pretty trivial so I'll commit in a day or two.
