    (%F14 1 0 0)))

calling

(baz 1 2 3)

in the REPL on x8664 reports that (non-volatile) registers were clobbered in the call.

This worked correctly in earlier releases; it seems to have broken around the time that the x86 backend started trying to "elide" speculative push/pop pairs.

See attached transcript, I think this is related to the changes made for 10.8 mentioned on the mailing list.

I tried r15564 which I think is current at the moment.
