commit 5b9f6cc4be80527177ee4b19a289116490881da0

    AMD64 - Make signals operational, fix reg mappings, fix %fs management, trace
    
    Adjust sigframe, trapframe, mcontext, ucontext, and regs.  Add tf_xflags
    too all structures.  Reorder struct regs to match the register layout
    in the other structures.
    
    Implement the commented out signaling code.  Signals now work, or at least
    do not crash programs.  Theoretically the FP state is also saved and restored.
    
    The exec() code failed to adjust gd_user_fs and gd_user_gs when setting
    the msr registers for the user %fs and %gs, causing %fs to unexpectedly
    change in running user programs.
    
    Implement trace/debug support functions to set %rip and to single-step.
    
    Define the missing vkernel flag FP_SOFTFP.
