RFR 8136349: Typos patch for nashorn sources submitted on Sep 10, 2015

[Sundararajan Athijegannathan]

Please review http://cr.openjdk.java.net/~sundar/8136349/ for 
https://bugs.openjdk.java.net/browse/JDK-8136349

This is a contribution by Ahmed Ashour. Please see this thread -> 
http://mail.openjdk.java.net/pipermail/nashorn-dev/2015-September/005206.html

This webrev was generated by after applying Ahmed's patch & then fixing 
the following manually on top of that:

1) File: NativeRegExp.java

    preceds -> precedes

2) File: CompiledFunction.java

    rest of -> "restOf" - this is a reference to "restOf" methods 
generated and so should not be "rest of".

Thanks,
-Sundar
