    x86: x86 core dump TLS
    
    This makes ELF core dumps of 32-bit processes include a new
    note type NT_386_TLS (0x200) giving the contents of the TLS
    slots in struct user_desc format.  This lets post mortem
    examination figure out what the segment registers mean like
    the debugger does with get_thread_area on a live process.
