Hi,

in revision 250048 the setting of cgraph's node versionable flag was
made conditional on optimization level, which is undesirable as there
may be other reasons to make a copy of a function, not just
optimization for example expansion to HSA which is what the PR 81477
is about.

Fixed thusly, the patch has passed bootstrap and testsuite on
x86_64-linux with HSA enabled and testing on an actual HSA-capable
machine.  I'm still waiting for results of LTO-bootstrap and since the
change was pre-approved by Honza in person, I will commit it if passes
that as well.

Thanks,

Martin
