Remove redundant use of REG_CLASS_NAMES maros

[Anatoliy Sokolov]

Hi.

This patch remove static reg_class_names array from  print_translated_classes and 
print_unform_and_important_classes functions. Global reg_class_names array is used 
instead.

Bootstrapped and reg-tested on x86_64-unknown-linux-gnu and
powerpc64le-unknown-linux-gnu.

OK for trunk?
