The reload error is caused by the "=rf" constraints in the various
patterns used for call_value. We also need to handle aggregrates
up to 128 bits. I have had a successful bootstrap with these fixes
but there are a number of regressions in the v3 testsuite which
I am still trying to get a handle on.
