Candidate patch

OK, thanks. This version drops the lra_in_progress hack and
makes the test symmetric.  As mentioned in the commit
message, I'd wondered about generalising it further and
allowing any 64-bit mode, but that seems unnecessarily
dangerous for stage 4.

The previous hack passed bootstrap & regtest on gcc112.
I'll try with this version too.
