expmed: Fix possible use of NULL_RTX return value from emit_store_flag

MSP430 does not support have any store-flag instructions, so
emit_store_flag can return NULL_RTX.  Catch the NULL_RTX in
expmed.c:expand_sdiv_pow2.

gcc/ChangeLog:

* expmed.c (expand_sdiv_pow2): Check return value from emit_store_flag
is not NULL_RTX before use.
