This is used by the LLVM backend in order to generate unique names for
temporary SSA values and functions.

All backends (e.g. arm, ppc, sparc, x86) share the same code for the following
functions:
  * find_const/2,
  * mk_data_relocs/2, and
  * slim_sorted_exportmap/3

This commit moves those definitions (along with some helper functions) in
misc/hipe_pack_constants.erl and adds the appropriate specs. This is a
structural change; no change in semantics intented.

The types array(), dict(), digraph(), gb_set(), gb_tree(), queue(),
set(), and tid() have been deprecated. They will be removed in OTP 18.0.

Instead the types array:array(), dict:dict(), digraph:graph(),
gb_set:set(), gb_tree:tree(), queue:queue(), sets:set(), and ets:tid()
can be used. (Note: it has always been necessary to use ets:tid().)

It is allowed in OTP 17.0 to locally re-define the types array(), dict(),
and so on.

New types array:array/1, dict:dict/2, gb_sets:set/1, gb_trees:tree/2,
queue:queue/1, and sets:set/1 have been added.

OTP-10106
OTP-10107

          environment after a number of bugs are fixed and some features
          are added in the documentation build process.

          - The arity calculation is updated.

          - The module prefix used in the function names for bif's are
            removed in the generated links so the links will look like

            http://www.erlang.org/doc/man/erlang.html#append_element-2

            instead of

            http://www.erlang.org/doc/man/erlang.html#erlang:append_element-2

          - Enhanced the menu positioning in the html documentation when a
            new page is loaded.
          - A number of corrections in the generation of man pages (thanks
            to Sergei Golovan)
          - Moved some man pages to more apropriate sections, pages in
            section 4 moved to 5 and pages in 6 moved to 7.
          - The legal notice is taken from the xml book file so OTP's
            build process can be used for non OTP applications.
