[Greedy RA] Add a check to MachineVerifier
If Virtual Register is alive in landing pad its def must be
before the call causing the exception or it should be statepoint instruction itself and
in this case def actually means the relocation of gc pointer and is alive in
landing pad.
The test shows the triggering this check for an option under development
use-registers-for-gc-values-in-landing-pad which is off by default until
it is functionally correct.
