hg: jdk8/tl/langtools: 8004504: ListBuffer could reuse List.nil() as the sentinel element

[Jonathan Gibbons]

With this changeset, we welcome Jan Lahoda as an Author directly
providing changesets for javac in JDK 8.  Jan is on the NetBeans team,
and helps provide the red squiggly lines and other features in the Java
editor windows, amongst his other duties, so he is more than a little
familiar with the javac codebase. :-)

He's already provided a number of contributions --  just do
     "hg log -k lahoda"
in a langtools repository to get a list.
