Note that the fix solves the problem just partly.  We now have duplicate
definition of the symbol with -fno-use-linker-plugin -flto-partition=1to1
This is because the problem in can_prevail predicate mentioned in the mail.
For this reason I left out the testcase from final commit (didn't noticed the
problem earlier since I tested it with plugin enabled only)
