bug#29334: 25.3; compiled commands don't respect special interactive expressions

[Allen Li]

Repro:

1. emacs -Q
2. Mark some text in the buffer
3. M-x append-to-buffer RET *scratch* RET
4. C-x ESC ESC

Expected last command:

(append-to-buffer "*scratch*" (region-beginning) (region-end))

Actual last command:

(append-to-buffer "*scratch*" 1 145)

If you then go and re-evaluate append-to-buffer (thus loading the
source version instead of the compiled version, you get

(append-to-buffer "*scratch*" (region-beginning) (region-end))

Thus, it looks like the compiled command doesn't handle special
interactive forms correctly.
