    traps: x86_64: add TRACE_IRQS_OFF in paranoidentry macro
    
    Add TRACE_IRQS_OFF just before entering the C code.
    
    All exceptions are taken via interrupt gates. If irq tracing is
    enabled, it should be notified as soon as possible. Interrupts
    are only (conditionally) re-enabled in C code.
