In the current implementation, compilation would fail because
operator<< is not defined for enum classes. For others, the compiler
finds more than one operator<<, so it fails because it's ambiguous.
This CL fixes this by printing the integer value for enums, uses the
operator<< for all values that support it, and prints "<unprintable>"
otherwise.
Also, lots of unit tests.

I want to reuse the PassType helper in another CL, thus move it from
logging.h to template-utils.h, and rename it to pass_value_or_ref to
match other helpers there.
Also, add a boolean template parameter to declare whether array
dimensions should be removed. The default is to do so, which helps to
reduce the number of template instantiations by always passing arrays
as pointers.
Also, fix the usages in logging.h to actually use that helper when
instantiating other template functions. This will reduce the number of
instantiations.
And finally, we now have unit tests for the template utils, to document
what we expect, and test that this works on all architectures.
