Support for running tests is done for all systems. This includes adding code to run tests on windows x86, which was missing. Currently only jdk_tier1 on linuxes and macos is enabled, as currently only this is passing without failures (see details lower). Testing on windows is currently disabled (no tier1 groups are passing there currently). Disabled tests can be easily enabled once, they are fixed. Ultimate goal is of course to run all tier1 groups (jdk_tier1, langtools_tier1, hotspot_tier1) on all platforms.

Hmm, just seen this. I'm not keen on how much this is diverging from the other JDKs. We'll likely need to revert some of this when backporting bundle support.

Do we not need a test bundle for running the tests? I had a feeling that was the case, as 8u doesn't have GTest, but wasn't 100%
