    Description

      This change contains some basic adaptions needed for a full hotspot port for linux s390x.

      It defines the required macros, platform names and includes.

      The s390 port calles CodeCache::contains() in current_frame(), which is used in NMT. As NMT already collects stack traces before the CodeCache is initialized, contains() needs a check for this.

      Wherever a row of platforms are listed, I sorted them alphabetically.

      The jdk requires the file jvm.cfg.
