I noticed this when looking for other places to change HOST_WIDE_INT

occurrences when I changed the ones in hard-reg-set.h.

OK? Bootstrapped and tested on powerpc-apple-darwin.

Thanks,

ChangeLog:
	else
	  {
-	    HOST_WIDE_INT in_table
+	    HOST_WIDEST_FAST_INT in_table
	      = TEST_HARD_REG_BIT (hard_regs_in_table, regno);


Uh, isn't the result of TEST_HARD_REG_BIT 0 or 1?
If so, why is this HOST_WIDE_* to begin with?
