* Initial commit with a lot of testing stuff. * Partial Unmap Cleanup Part 1 * Fix some minor issues, hopefully windows tests. * Disable partial unmap tests on macos for now Weird issue. * Goodbye magic number * Add COMPlus_EnableAlternateStackCheck for tests `COMPlus_EnableAlternateStackCheck` is needed for NullReferenceException handling to work on linux after registering the signal handler, due to how dotnet registers its own signal handler. * Address some feedback * Force retry when memory is mapped in memory tracking This case existed before, but returning `false` no longer retries, so it would crash immediately after unprotecting the memory... Now, we return `true` to deliberately retry. This case existed before (was just broken by this change) and I don't really want to look into fixing the issue right now. Technically, this means that on guest code partial unmaps will retry _due to this_ rather than hitting the handler. I don't expect this to cause any issues. This should fix random crashes in Xenoblade Chronicles 2. * Use IsRangeMapped * Suppress MockMemoryManager.UnmapEvent warning This event is not signalled by the mock memory manager. * Remove 4kb mapping
