Quentin Colombet f4848d8e0c [ImplicitNullChecks] Properly update the live-in of the block of the memory operation.
We basically replace:
HoistBB:
cond_br NullBB, NotNullBB

NullBB:
  ...

NotNullBB:
  <reg> = load

into
HoistBB
<reg> = load_faulting_op NullBB
uncond_br NotNullBB

NullBB:
  ...

NotNullBB: ## <reg> is now live-in of NotNullBB
  ...

This partially fixes the machine verifier error for
test/CodeGen/X86/implicit-null-check.ll, but it still fails because
of the implicit CFG structure.
