It would seem a good idea to enable testing of these functions as well.  
fp-int-convert.h contains logic also present in a few other places in the 
testsuite.

/* Not all platforms support TImode integers; logic as in
   gcc.dg/titype-1.c.  */
#if (defined(__LP64__) && !defined(__hppa__)) || defined(_WIN64)
typedef int TItype __attribute__ ((mode (TI)));
typedef unsigned int UTItype __attribute__ ((mode (TI)));
#else
typedef long TItype;
typedef unsigned long UTItype;
#endif

If this target now supports TImode properly, perhaps that logic needs 
updating in whatever places have it to enable TImode for this target.
