Vlad's recent IRA changes twiddled register allocation slightly causing some
tests to regress.  See 

http://gcc.gnu.org/jenkins

And look at the failures in the last 24hrs.

Anyway, I'm working through them right now.  This is the first issue. 
xstormy16 fails one test because of the register allocation difference.  I've
looked at the before/after and they appear equivalent in terms of code size and
likely performance.  So I'm just updating the test.

Given these tests are scanning for specific instruction sequences with
particular register numbers, I'm surprised have stable they've been over time.

Anyway, I'm committing this to the trunk momentarily and will start a fresh
xstormy16 build.
