This lets us use libcapstone directly from miniruby so we don't need a
Ruby Gem to to dev work.
Example usage:
```ruby
def foo(x)
if x < 1
"wow"
else
"neat"
end
end
iseq = RubyVM::InstructionSequence.of(method(:foo))
puts UJIT.disasm(iseq)
100.times { foo 1 }
puts UJIT.disasm(iseq)
```
Then in the terminal
```
$ ./miniruby test.rb
== disasm: #<ISeq:foo@test.rb:1 (1,0)-(7,3)> (catch: FALSE)
local table (size: 1, argc: 1 [opts: 0, rest: -1, post: 0, block: -1, kw: -1@-1, kwrest: -1])
[ 1] x@0<Arg>
0000 getlocal_WC_0 x@0 ( 2)[LiCa]
0002 putobject_INT2FIX_1_
0003 opt_lt <calldata!mid:<, argc:1, ARGS_SIMPLE>
0005 branchunless 10
0007 putstring "wow" ( 3)[Li]
0009 leave ( 7)[Re]
0010 putstring "neat" ( 5)[Li]
0012 leave ( 7)[Re]
