[DebugInfo][InstrRef] Avoid a crash from mixed variable location modes

Variable locations now come in two modes, instruction referencing and
DBG_VALUE. At -O0 we pick DBG_VALUE to allow fast construction of variable
information. Unfortunately, SelectionDAG edits the optimisation level in
the presence of opt-bisect-limit, meaning different passes have different
views of what variable location mode we should use. That causes assertions
when they're mixed.

This patch plumbs through a boolean in SelectionDAG from start to
instruction emission, so that we don't rely on the current optimisation
level for correctness.
