[SG10] Macro name for N3657

Here is the concluding message in the thread about the macro name for
heterogeneous comparison lookup for associative containers.

(Frankly, I didn't try to follow the logic; I was just happy the discussion
eventually came in for a landing with the authors all satisfied.)

Enjoy. :-)

Hmm, that's a good point. I'm fine with "generic" here.

Sorry to chime in late, but I object to
__cpp_lib_transparent_associative_lookup: comparison might be
transparent, but lookup (which is the feature, comparison only the
means) is generic. Much as polymorphic lambdas are generic but not
transparent. My vote goes then to __cpp_lib_generic_associative_lookup
(but will be happy with whatever the final decision is.)
