How much more memory?  DIAGNOSTIC is supposed to be reasonably cheap,
mostly cheap predicted-not-taken branches in assertions.  Should we
move more things to DEBUG instead for expensive checks and higher
memory usage?

What history did you check?  It has always been disabled in every
release branch.  See, e.g., this commit on the netbsd-9 branch:

http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/arch/amd64/conf/GENERIC?rev=1.531.2.4&content-type=text/x-cvsweb-markup&only_with_tag=netbsd-9

I checked every branch back to netbsd-2 and found it disabled.

I assume there must be a procedure somewhere that already has this!
