    Access the cp15.c13 TLS registers directly with TCG ops instead of with
    a slow helper. If the the cp15 read/write was not TLS register access,
    fall back to the cp15 helper.
    
    This makes accessing __thread variables in linux-user when apps are compiled
    with -mtp=cp15 possible. legal cp15 register to acces from linux-user are
    already checked in cp15_user_ok.
    
    While at it, make the cp15.c13 Thread ID registers available only on
    ARMv6K and newer.
