(Freeze_Entity): check for tagged type in imported C subprogram
(Freeze_Entity): check for 8-bit boolean in imported C subprogram
(Freeze_Entity): check for convention Ada subprogram pointer in
imported C subprogram.
(Freeze_Fixed_Point_Type): In the case of a base type where the low
bound would be chopped off and go from negative to zero, force
Loval_Excl_EP to be the same as Loval_Incl_EP (the included lower
bound) so that the size computation for the base type will take
negative values into account.

* adaint.c (__gnat_pthread_setaffinity_np): New routine. A dummy
version is provided for older GNU/Linux distribution not
supporting thread affinity sets.

call.
(bit_field): New packed boolean type used by cpu_set_t.
(cpu_set_t): New type corresponding to the C type with
the same name. Note that on the Ada side we use a bit
field array for the affinity mask. There is not need
for the C macro for setting individual bit.
(pthread_setaffinity_np): New imported routine.
* s-taprop-linux.adb (Enter_Task): Check that the CPU affinity mask is
no null.
(Create_Task): Set the processor affinity mask if information
is present.
