* fixed unaryminus overflow check for high level targets (call helper via

    hlcg, and use compproc name)
  * fixed unaryminus overflow check for targets that use the generic code
    for both 32 and 64 bit integers even if their "native" integer size
    is 32 bit (by not checking against low(aint), but opsize.low)
