[Bug debug/25468] [4.0/4.1/4.2 Regression] -g makes g++ loop forever

We do the loop-and-putc thing in ASM_OUTPUT_LIMITED_STRING and in
dw2_asm_output_nstring as well.  Probably it's best to add some kind of generic
"escaped string" print function, something like the one below that I'll try to
actually make work:

void
asm_output_string_with_escapes (const char *str, size_t len,
                                const char escapes[255],
                                const char *escapes_fmt /* e.g. "\\%03o" */
                                size_t escapes_fmt_len)
{
  size_t i, j, len, escaped_len;
  char *escaped_str;

  escaped_len = len;
  for (i = 0; i < len; i++)
    {
      int c = str[i];
      if (c == '\"' || c == '\\')
        escaped_len++;
      else if (escapes[c])
        escaped_len += escapes_fmt_len;
    }

  str = xmalloc (escaped_len + 1);

  for (i = 0, j = 0; i < len; i++)
    {
      int c = str[i];
      if (!escapes[c])
        {
          if (c == '\"' || c == '\\')
            escaped_str[j++] = '\\';
          escaped_str[j++] = c;
        }
      else
        {
          /* ??? Must also handle things like \t and \b here.  */
          snprintf (&escaped_str[j], escapes_fmt_len, escapes_fmt, c);
          j += escapes_fmt_len;
        }
    }
  escaped_str[j] = '\0';
  fputs (escaped_str, asm_out_file);

  free (escaped_str);
}
