8005978: shell tests need to use the $COMPILEJDK for javac, jar and other tools

[Alan Bateman]

I'm currently trying to run the jdk tests on the compact profiles. As 
the profile builds are runtimes only, they don't have tools such as 
javac and so need to be run with both -jdk and -compilejdk. That works 
okay except for the shell tests because many of them launch the "javac" 
or "jar" tools directly and so fail because the runtime under test 
($TESTJAVA) is not a JDK. I'd like to update the shell tests to use the 
tools in $COMPILEJAVA, this is the JDK specified to jtreg with 
-compilejdk or it's the same as $TESTJAVA when -compilejdk is not specified.

The webrev with the proposed changes is here:

For the most part this is just s/TESTJAVA/COMPILEJAVA/ although there 
are a couple of subtle things to watch out for - for example tool tests 
should be testing the tools in $TESTJAVA, not $COMPILEJAVA. Many of the 
shell tests were created to be runnable outside of jtreg so I've 
preserved this where it was previously supported.

I should note that this is not all of the shell tests, I don't have time 
to fix the tests in areas that aren't interesting for the profiles so 
contributions to do more would be welcome.  Another thing is that a lot 
of these shell tests are old tests and a lot of them don't really need 
to be shell tests. I mention this because another great effort would be 
be gradually replace many of these shell tests.
