Don't always zero pad in print_*_chars
This changes print_octal_chars and print_decimal_chars to never zero pad, and changes print_binary_chars and print_hex_chars to only optionally zero-pad, based on a flag. ChangeLog 2017-06-12 Tom Tromey <tom@tromey.com> PR exp/16225: * valprint.h (print_binary_chars, print_hex_chars): Update. * valprint.c (val_print_type_code_int): Update. (print_binary_chars): Add "zero_pad" argument. (emit_octal_digit): New function. (print_octal_chars): Don't zero-pad. (print_decimal_chars): Likewise.
