M138 merge issues:

src/maglev/maglev-code-generator.cc:
  in MaglevCodeGeneratingNodeProcessor::Process():
  regalloc_info() doesn't exist in M138, called it directly using
  the node object:
-      DCHECK(!node->regalloc_info()->has_register());
+      DCHECK(!node->has_register());

The regalloc should clear the node allocations when it is done.
Failing to do so can cause the codegen to use stale register state.
In this concrete example the exception handler trampolines would not
load from the spill slot due to the left over allocation.
