Request for approval for 8024356: Double.parseDouble() is slow for long Strings

[Brian Burkhalter]

This is a request for a partial backport from JDK 8. The code in question was part of a large patch which has been integrated now for about three months.

Issue:		http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=8024356
Webrev:		http://cr.openjdk.java.net/~bpb/8024356/
Review:		http://mail.openjdk.java.net/pipermail/core-libs-dev/2013-September/020837.html

Assuming this is approved, I will need a JDK 7 Committer for push it.

Thanks,

Brian
