[clang][NewPM] Do not eliminate available_externally durng `-O2 -flto` runs

Authored by leonardchan on Jun 19 2019, 4:32 PM.



This fixes CodeGen/available-externally-suppress.c when the new pass manager is turned on by default. available_externally was not emitted during -O2 -flto runs when it should still be retained for link time inlining purposes. This can be fixed by checking that we aren't LTOPrelinking when adding the EliminateAvailableExternallyPass.
