RFR: 8145132: Initial updates for ios x86_64 mobile/dev builds.

[Gary Adams]

I've revised the original webrev based on some feedback received.
    - reverted white space only changes
    - proper copyrights on the new files
    - some hotspot files contained previously removed code

   Webrev; http://cr.openjdk.java.net/~gadams/8145132/webrev.01/

Planning to push this first batch tomorrow.
