http://cr.openjdk.java.net/~iklam/jdk11/8191375-cds.tests.vmprop.v01/

Summary:

1. Added the new property "@require vm.cds.archived.heap". This replaces 
various
    ad-hoc settings like the following, which is hard to maintain:

    * Feature support: G1GC only, compressed oops/kptrs, 64-bit os, not 
on windows
    * @requires (sun.arch.data.model != "32") & (os.family != "windows")
    * @requires vm.cds
    * @requires vm.gc.G1


2. Also did some clean up such as removing duplicated lines of "@require 
vm.cds"
    in some tests

3. Removed explicit settings of -XX:-UseCompressedOops, -XX:+UseGCGC, 
etc, that
    are now implied by "@require vm.cds" or "@require vm.cds.archived.heap"

4. Removed unnecessary '@require vm.gc == "null"' from a few test cases.
    (It is only needed by tests that explicitly choose GC types, but 
somehow it's
    been leaked to other tests due to copy-paste).

I've tested locally with jtreg:

   - no explicit setting of GC
   - explicitly set GC with -vmoptions:-XX:+UseG1GC
   - explicitly set GC with -vmoptions:-XX:+UseParallelGC

Testing with mach5 with tiers 1-3 now.

Thanks
