RFR: 8201274: Launch Single-File Source-Code Programs

[Jonathan Gibbons]

Here's an update to the previously proposed patch for JEP 330: Launch 
Single-File Source-Code Programs.
It includes all review feedback so far. The changes are mostly minor, 
but with the addition of more test cases.

The webrev includes a delta-webrev for those that just want to see what 
has changed since last time.

Full webrev: http://cr.openjdk.java.net/~jjg/8201274/webrev.mq/index.html

     Original webrev: 
http://cr.openjdk.java.net/~jjg/8201274/webrev.mq/webrev.v1/index.html
     Delta webrev: 
http://cr.openjdk.java.net/~jjg/8201274/webrev.mq/webrev.v2/index.html

Note that the work is temporarily blocked by JDK-8202387: javac 
--release 11 not supported.
A fix for that is underway and in review: 
http://mail.openjdk.java.net/pipermail/compiler-dev/2018-May/011868.html
This work has been tested using a workaround for this issue, and will be 
tested again when the real fix is in place.
