        src/share/man/man4: options.4

Log Message:
Sync DIAGNOSTIC performance comments with historical reality.

Somehow, options(4) ended up with a bizarre claim that DIAGNOSTIC can
reduce performance by 15%.  While that might have been true at some
isolated point due to a bug, it's an outlier.  Since at least 2BSD,
DIAGNOSTIC has added asserts, resulting in at most
difficult-to-perceived performance degredation, and many people have
been running production systems (meaning systems they intend to use,
rather than debugging targets) with this option.    (The decision a
while ago to enable DIAGNOSTIC in -current's GENERIC reflects this; if
it really were a 15% hit such enabling by default would be unreasonable.)
