RFR (S): 8006965: test_gamma should run with import JDK

[Christian Thalinger]

I talked to a lot of people about this today.  What we really want is to not run tests when we build.  Mikael and I were looking into how we could do that without gamma and there is a way:

http://cr.openjdk.java.net/~twisti/8006965/

This would be the first of three fixes:

Fix 1)  The patch above removes test_gamma and uses some weirdness in the VM (-Dsun.java.launcher=gamma) to run it with an existing JDK; add test_{product,fastdebug,debug} targets

Fix 2)  Remove gamma and all the ugly code that comes with it (copies of the jdk launcher in hotspot and other pieces); make the hotspot script work like the test targets in Fix 1

Fix 3)  Remove the -Dsun.java.launcher=gamma and possibly replace the existing -Dsun.boot.library.path weirdness by explicit command line options like -Xbootlibrarypath:{/p,/a}
