Hi,

My patch r174586 on trunk was a bit incomplete and causes
PR49305 on sh2a target.  The attached patch is to fix it.
Tested on sh-elf and sh4-unknown-linux-gnu and applied on
trunk.

BTW, when looking into PR, I noticed that we forgot to utilize
32-bit mov.w instructions on sh2a while 32-bit mov.[bl]
instructions are enabled on that target already.  I'll prepare
the patch for it.

Regards,
	kaz
