The BEAM disassembler used the atom 'none' to signify the absence
of a compile_info chunk in a .beam file. This clashes with the type
declaration of the compile_info field of a #beam_file{} record as
containing a list. Use [] to signify the absence of this chunk.
This simplifies the code and avoids a dialyzer warning.
For fixing a similar problem and for consistency, changed also the
return type of the attributes field of the #beam_file{} record.
This required a change in the beam_disasm test suite.

* bjorn/compiler/options/OTP-9752:
filename documentation: Recommend against using filename:find_src/1,2
Teach filename:find_src/1,2 to handle slim or stripped BEAM files
filename: Eliminate failing call to Mod:module_info(source_file)
filename.erl:filter_options/1: Remove handling of dead options
compiler: Don't include {cwd,_} in module_info(compile)
compiler: Don't include source code options in module_info(compile)
hipe: Teach hipe to handle slim or stripped BEAM files

Compiling single functions (as opposed to whole modules) to native
code complicates code management in HiPE. It would also vastly
complicate whole-module optimizations, such as returning multiple
return values instead of tuples within a module.
As a first step, remove the external interface for the single
compilation feature. In the future, there are many things that
could be restructured and simplified.

hipe:load/1 (and unexported hipe:load/2) just did not work. Calling it
would fail with a badmatch because only the hipe chunk was passed to
do_load/3's third parameter called WholeModule. Since this parameter is
then passed to beam_lib:all_chunks/1 which accepts the whole module as a
binary as well as a path to the beam file, and since a path is exactly
what we have in load/2, the fix consists in letting do_load/3 accept a
path and passing it from load/2.
