Rudimentary support for disassembling rb_iseq_t
I need to disassemble instruction sequences while debugging, so I wrote this. Usage is like this: ``` (lldb) p iseq (rb_iseq_t *) $147 = 0x0000000101068400 (lldb) rbdisasm iseq 0000 putspecialobject( 3 ) 0002 putnil 0003 defineclass( ID: 0x560b, (rb_iseq_t *)0x1010681d0, 2 ) 0007 pop 0008 putspecialobject( 3 ) 0010 putnil 0011 defineclass( ID: 0x56eb, (rb_iseq_t *)0x101063b58, 2 ) 0015 leave ``` Also thanks a ton to @kivikakk helping me figure out how to navigate LLDB's Python 😆
