Fix minor length computation on stormy16

Today's build of xstormy16-elf failed due to a branch to an out of range
target.  Manual inspection of the assembly code for the affected function
(divdi3) showed that the zero-extension patterns were claiming a length
of 2, but clearly assembled into 4 bytes.

This patch adds an explicit length to the zero extension pattern and
appears to resolve the issue in my test builds.

	* config/stormy16/stormy16.md (zero_extendhisi2): Fix length.
