Hi,

This fixes an SH64 problem which was introduced in r185534 and went
unnoticed until recently.  There, the extendqihi2 insn was converted to
an expander and the TARGET_SH1 condition was wrongly omitted.  Tested
with 'make all-gcc' on sh-elf and sh64-elf.  Committed on trunk as
r218469, on 4.9 as r218470 and on 4.8 as r218471.

Cheers,
Oleg

gcc/ChangeLog:
	PR target/50751
	* config/sh/sh.md (extendqihi2): Allow only for TARGET_SH1.
