Committed in r273783 after retesting and including a test for
the warning that I had left out of the patch I posted here.

PS I suspect some of the tests I added might need tweaking on
big-endian systems. I'll deal with them tomorrow.
And maybe also strictly aligned targets. A sparc-solaris2.11 cross
shows these failures. It looks like it doesn't like something about
some of the 64 bit stores in the tests.
