    ARMV7 and Google/Snow: Add exception support code to the ramstage
    
    This is previously used exception code from libpayload.
    On startup it installs and then tests an exception handler.
    The test is an unaligned memory operation.
    
    Yes, we've seen what might be exceptions in the ramstage, and
    it makes sense to handle them. This code is identical in structure
    and operation to the previously committed payload exception handler,
    though we reserve the right to change it as circumstances require.
    
    The remaining question is whether we need it in romstage.
