DRY: use existing method Type::getInternalName in Type::appendDescriptor

[stsypanov]

String name = currentClass.getName();
int nameLength = name.length();
for (int i = 0; i < nameLength; ++i) {
  char car = name.charAt(i);
  stringBuilder.append(car == '.' ? '/' : car);
}

this code appends the name of currentClass having all dots replaced with '/'. However the same class already contains method doing exactly the same

public static String getInternalName(final Class<?> clazz) {
  return clazz.getName().replace('.', '/');
}

This one is not only more readable and likely to be faster as it yields the whole String at once instead of appending char by char inflating original StringBuilder.

You have a point there. However, this code is a repackaged fork of https://gitlab.ow2.org/asm/asm/commits/master, so any such refactorings should really start there... and we'll automatically pick it up for our fork at our next sync point then.
