Clean up generated operator<<(os, enum).

Pass enums by value instead of const reference.

Do not generate operator<< sources for headers that have no
enums or no declarations of operator<<. Do not define the
operator<< for flag enums; these were unused anyway.

Add generated operator<< for some enums in nodes.h . Change
the operator<< for ComparisonBias so that the graph
visualizer can use it but do not use the generated
operator<< yet as that would require changing checker tests.

Test: m test-art-host-gtest
Test: testrunner.py --host --optimizing
