Log Message:
enhance MI pthreads code to support hppa:
 - statically initialize all global spin locks.  on hppa, 0 means
   the lock is held, so leaving them with the default value doesn't work.
 - compare functions pointers using a function-pointer type rather than
   an integral type.  on hppa, function pointers may be indirect,
   so we need to trigger gcc to emit calls to the function-pointer
   canonicalization routines in the millicode.
 - on hppa the stack grows up, so handle that using the STACK_* macros.
