    Attachment: Fix-support-of-SOE-and-other-runtime-exceptions-in-VM-native-code.txt

Fix support of SOE and other runtime exceptions in VM native code.

The fix consists in:
    enable lazy exception scheme,
    remove fake assertions,
    provide separate way of throwing exception for native code from exn_athrow_regs,
    add test excetion.FinalizeStackTest to smoke tests to check this changes.
