DUALNUM: Add missing type conversion for FORI slots.

Reported by Sergey Kaplun.

(cherry picked from commit 406cf69b3)

`rec_for_loop()` narrows the FORL index values by getting them from the
runtime. In case when the `start`, `stop`, `step` control variables are
already loaded to the slots, their TRef isn't converted to the
corresponding type. This leads to the following inconsistent IR dump and
to the assertion failure later:
| 0002 > int SLOAD  10   TCI
| 0003   int ADD    0002  +1.
| 0004 > int LE     0003  +1.
| 0005   int ADD    0003  +1.
| 0006 > int GT     0005  +1.

This patch adds the missing type conversion.
