improve C0 coverage of insns.def from 65.9% to 96.1%

While I was developing my private topic branch I found that the VM
itself is not tested very much in `make test` tests.  Of course
`make test-all` covers vast majority of the VM but running that task
is not an immediately possible thing when we are touching the VM.  In
order to boost development in a rapid cycle I decided to add some
tests to the bootstraptest.  Here it is.

	* test_insns.rb: new test that covers insns.def.

	* runner.rb (#assert_equal): pass extra options to the target
	  so that we can test frozen_string_literal: true situation.
