More minor fallout from Vlad's IRA changes.
Previously this test used r3 to hold a value across a call (it's an ipa-ra
test). After Vlad's changes we're using r1 instead.
This patch makes the obvious change to pattern we can for which should bring
the test back to a passing status.
There's a note about r3 being special on thumb1 and the pattern check is
skipped for thumb1. That special casing my not be necessary anymore -- I leave
that to the ARM maintainers to resolve one way or the other.
Committing on the trunk momentarily.

Any of r1, r2, r3 could be chosen for the 'save' register, so why not
put that in the regexp?
Something like:
+/* { dg-final { scan-assembler-times "mov\tr[123], r0" 1 { target { !
arm_thumb1 } } } } */
And then we are future-proof.
R.
