In addition to detect dead canary, we try to detect the very moment
when we smash the stack top. Requested by k0kubun:

* template/limits.c.tmpl (Init_limits): rename RbConfig::Limits as
RbConfig::LIMITS, constants other than class or module are all
uppercase with underscores by convention.

The same optimization used for "literal string".freeze
can easily apply to uminus without introducing any
compatibility problems.

Because our tests now have several places where FIXNUM_MAX is needed,
we decided to provide it along with several other constants.
* template/limits.c.tmpl: new file, defining RbConfig::Limits
* ext/rbconfig/sizeof/depend (limits.c): rule to generate limits.c
* test/-ext-/num2int/test_num2int.rb: use RbConfig::Limits
* bootstraptest/test_insns.rb: ditto.
* .gitignore: ignore new generated file.

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.
