RFR : 8013528 : (XS) Provide SharedSecrets access to String(char[], boolean) constructor

[Mike Duigou]

Hello all;

Since this code will be introduced without any usages I decided it was critical to make a stand alone unit test. I've updated the webrev:

http://cr.openjdk.java.net/~mduigou/JDK-8013528/1/webrev/

The webrev mistakes my hg copy for a rename... Ignore that. Capturing the provenance of the test file probably isn't critical since the file is repurposed for a different test, but I prefer to have the origin tracked rather than use a non-vcs copy.

I also made the other changes suggested by reviewers.

Thanks

Mike

It adds an internal mechanism for performance sensitive usages to create a string from a provided character array without copying that array. This saves both in the allocation (and subsequent GC) as well as the copying of the characters. There are a few places in the JDK that return Strings which can benefit from this change.
