It does not make sense to return multiple values from a sequence
argument and the Kernel Erlang passes can't cope with it.
The linting pass now knows how to detect this kind of defunct code and
the Core code folding pass is changed to not generate code like that
when optimizing away multiple-valued lets in effect mode.

servers behaves
Rationale:
Some applications (like erlide) have code to be loaded dynamically on a
node. It may be slow to load everything upfront every time, so if the
node is in interactive mode, we would like to just append to the load
path. Currently, there is no direct way to detect if the node is running
in embedded mode or not so that we can do the right thing.

Jinterface uses System.getProperty("user.home") to locate the user's home
and the cookie file. On Windows, the result might be different than the
value used by Erlang, which looks first to the HOMEDRIVE and HOMEPATH
variables.
The fix makes jinterface use the same logic.

The elems field would remain unitialized if the count parameter is zero in constructor

All guards BIFs are auto-imported. That can be verified like this:
[] = [{F,A} || {erlang,F,A} <- erlang:system_info(snifs),
erl_internal:guard_bif(F, A),
not erl_internal:bif(F, A)]
Therefore, calling a guard BIF in a guard without a module name
is always allowed (provided that there is not a local function or
an import with the same name), and therefore we can remove the
error reporting code. But keep an assertion so that we will find
out if any non-auto-imported guard BIFs are added in the future.

In code such as:
X / 2
the following code would be output from beam_type for the division:
{fconv,{x,0},{fr,0}}.
{fconv,{integer,2},{fr,1}}.
fclearerror.
{bif,fdiv,{f,0},[{fr,0},{fr,1}],{fr,0}}.
That is, the integer 2 would be converted to the float 2.0 at
run-time by "{fconv,{integer,2},{fr,1}}". Make sure that we do
the conversion at compile time.

The BEAM loader will put floating point constants into the
literal pools for the module, but it will not check for duplicates.
We can do much better by having the compiler use the literal
pool for floating point constants.

If using gcc 4.5 from MacPorts, or probably any other
third party "real" gcc to compile the VM, an unusable
wx-driver was created, as the wx application requires
the apple compilers for all files (not only ObjC)
since we started to support Cocoa wxWidgets.

When starting up an Erlang node using a node name that is already in
use, the new node used to crash with output starting with this message:
{error_logger,{{2013,1,25},{16,0,42}},"Protocol: ~p: register error: ~p~n",["inet_tcp",{{badmatch,{error,duplicate_name}},[{inet_tcp_dist,listen,1,[.....
With this change, the first line in the output changes to:
{error_logger,{{2013,1,25},{16,40,41}},"Protocol: ~tp: the name foo@localhost seems to be in use by another Erlang node",["inet_tcp"]}
