Make more use of in_hard_reg_set_p
An upcoming patch will convert hard_regno_nregs into an inline
function, which in turn allows hard_regno_nregs to be used as the
name of a targetm field. This patch rewrites a use that can use
in_hard_reg_set_p instead.

gcc/
* ira-costs.c (record_operand_costs): Use in_hard_reg_set_p
instead of hard_regno_nregs.
