[GVN+LICM] Use line 0 locations for better crash attribution

Authored by vsk on Apr 19 2019, 12:05 PM.



This is a follow-up to r291037+r291258, which used null debug locations
to prevent jumpy line tables.

Using line 0 locations achieves the same effect, but works better for
crash attribution because it preserves the right inline scope.
