* time.c (time_localtime): check if `vtm.zone` is a simple zone name string before trying to call the conversion method. since r64952, `Time.getlocal` on UTC time has lost the performance about 45%, due to this call. the performance is about 90% of r64951 by avoiding it. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65360 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2018-07-04Optimize Time.utcnaruse
Time.utc uses timegmw() and it uses leap second information. If the given time is larger than known_leap_seconds_limit, it calls find_time_t, which uses localtime(3) and calls stat(2) in it. This patch avoid it by setting known_leap_seconds_limit to 0 if the timezone doesn't have leapsecond information (if no leap second is found "now", I assume the timezone doesn't have leapsecond information).
