Subject: Put misc/gdb.py [experimental]

This works like:

```
(gdb) cfp
CFP (count=3, addr=0x7ffff73fef50):
$1 = {pc = 0x555556bf7818, sp = 0x7ffff72ff078, iseq = 0x7ffff2603270, self = 140737344619296, ep = 0x7ffff72ff058, block_code = 0x0,
  __bp__ = 0x7ffff72ff060, jit_return = 0x555558c2b000}

Stack (size=3):
[0] FIXNUM: 1
[1] T_STRING: "" bytesize:0 (embed) encoding:1 coderange:7bit $2 = (struct RString *) 0x7ffff249ea80
[2] [PROMOTED] T_OBJECT: $3 = {flags = 21474844769, klass = 140737344040416}
$4 = {0x24, 0x24, 0x24}

(gdb) cfp + 1
CFP (count=3, addr=0x7ffff73fef90):
$5 = {pc = 0x5555567a78f8, sp = 0x7ffff72ff040, iseq = 0x7ffff26032d0, self = 140737344619296, ep = 0x7ffff72ff038, block_code = 0x0,
  __bp__ = 0x7ffff72ff040, jit_return = 0x555558c2b000}

Stack (size=0):
