* ira.c (setup_pressure_classes): Don't check register move cost
for classes with one registers. Don't add pressure class if there
is a pressure class with the same available hard registers.
Check contains_reg_of_mode. Fix a typo in collecting
temp_hard_regset. Ignore hard registers not belonging to a class.
