gcc44-pr39106.patch
Patch I'm going to bootstrap/regtest. The problem is that
cgraph_function_versioning copies the whole FUNCTION_DECL node, including
DECL_LANG_SPECIFIC etc. and then the original bar function doesn't need to be
emitted (so emit_associated_thunks langhook isn't called for it), but when
it is called on the versioned bar function, it will emit thunks for
non-existing
function. As emit_associated_thunks langhook does nothing if !DECL_VIRTUAL_P,
I think the easiest fix is to clear this bit.
