RFR [JEP 220] Modular Run-Time Images - compact profiles footprint

The footprint of the compact profiles have been inflated by ~12Mb each
after the JEP 220 changes.
# du -s -h j2re-compact1-image
# du -s -h j2re-compact2-image
# du -s -h j2re-compact3-image
# du -s -h jre-compact1
# du -s -h jre-compact2
# du -s -h jre-compact3
The attached file compact1.diff.tar.gz contains the list diff of the
files bundled in the
j2re-compact1-image/lib/rt.jar compared to jre-compact1/lib/*.jimage
most of the class diff is located in
sun/util/resources <- a lot of extra internationalized classes
sun/text/resources <- a lot of extra internationalized classes

>> This is a review request for the changes for JEP 220: Modular Run-Time Images .
>> There are a number of individuals responsible for these changes. Some, possibly not all, are explicitly listed in the 'To' section of this mail, and they will help address any comments arising from this review request.
>> The new run-time image structure is defined in JEP 220 , and can be seen as a result of building the staging forest , or in the early access builds .
>> Due to the significant impact of these changes, a JDK 9 promotion has been tentatively reserved for their integration. All comments are welcome, although given the nature of the changes then we might have to create separate issues in JIRA to address some of them later in jdk9/dev.
