https://codereview.chromium.org/22807003/diff/1/src/compiler.cc
File src/compiler.cc (right):

https://codereview.chromium.org/22807003/diff/1/src/compiler.cc#newcode451
src/compiler.cc:451: info_->set_bailout_reason(kBailedOutDueToDependentMap);
same naming nit here

https://codereview.chromium.org/22807003/diff/1/src/compiler.h
File src/compiler.h (right):

https://codereview.chromium.org/22807003/diff/1/src/compiler.h#newcode302
src/compiler.h:302:
!isolate()->optimizing_compiler_thread()->IsOptimizerThread());
IsOptimizerThread contains "if (!FLAG_parallel_recompilation) return false;", so
you don't need the || here.

https://codereview.chromium.org/22807003/diff/1/src/compiler.h#newcode303
src/compiler.h:303: abort_due_to_map_dependency_ = true;
naming nit: could be any dependency change, not just a map.
