Specifically: - Disable int128 tests on Windows, as MSVC cl.exe does not support int128, so we might not have been able to build the runtime with int128 support. - XFAIL the vptr tests as we lack Microsoft ABI support. - XFAIL enum.cpp as UBSan fails to add the correct instrumentation code for some reason. - Modify certain tests that build executables multiple times to use unique names for each executable. This works around a race condition observed on Windows. - Implement IsAccessibleMemoryRange for Windows to fix the last misaligned.cpp test. - Introduce a substitution for testing crashes on Windows using KillTheDoctor.
