When we leave SIE due to an exception, we'll still have guest values

prints. So let's fix that.

wouldn't it be cleaner to restore the registers in the interrupt
handler? (I thought we were already doing it)

You mean RESTORE_REGS_STACK? Please don't make me write this in assembly...

RESTORE_REGS_STACK is doing test/pgm register swapping, it doesn't care if the test registers are "host" or "guest" registers.
