Represents a register backup.

The exception wrapper constructs this structure before calling the exception handler, and saves it to the ThreadStruct for debug purposes.

When the exception handler returns, the wrapper pops it before returning to userspace, allowing precise control over register state. The only exception being .esp, which will not be reloaded into esp, see trap_gate_asm.
