If an allocate_zero instruction is fed to beam_block and the beam_type
pass is not used afterwards (e.g. with erlc +no_topt), the 'no_opt' atom
will be rejected by beam_flatten.

The compiler shouldn't crash when fed an already-optimised BEAM assembly file.

Change emacs erlang-mode to recognize EEP37 named funs so they're indented
properly. Specifically, modify erlang-partial-parse to allow for an
optional Erlang variable name to appear between the "fun" keyword and the
opening parenthesis of its argument list.

The current code for the evaluation of ordinary funs is dependent
on the order on variables in the fun environment as returned by
erlang:fun_info(Fun, env). As it happened, adding the code for
named funs changed the order in the environment for ordinary funs.
To avoid the problem in the future, make sure that we only have one
free variable in the funs that we will need to inspect using
erlang:fun_info(Fun, env).

This adds optional names to fun expressions. A named fun expression
is parsed as a tuple `{named_fun,Loc,Name,Clauses}` in erl_parse.
If a fun expression has a name, it must be present and be the same in
every of its clauses. The function name shadows the environment of the
expression shadowing the environment and it is shadowed by the
environment of the clauses' arguments. An unused function name triggers
a warning unless it is prefixed by _, just as every variable.
Variable _ is allowed as a function name.
It is not an error to put a named function in a record field default
value.
When transforming to Core Erlang, the named fun Fun is changed into
the following expression:
letrec 'Fun'/Arity =
fun (Args) ->
let <Fun> = 'Fun'/Arity
in Case
in 'Fun'/Arity
where Args is the list of arguments of 'Fun'/Arity and Case the
Core Erlang expression corresponding to the clauses of Fun.
This transformation allows us to entirely skip any k_var to k_local
transformation in the fun's clauses bodies.

Dialyzer so far only supported letrecs at the top-level
and comprehension-like letrecs (i.e. that were directly applied)
in their body.
This commit address this issue by storing in the callgraph
bound letrec labels pointing to their functions. This information
is then used by the dataflow to properly lookup recursive
definitions.

by making sure we at least can read the first four bytes
of a compiled regexp where the 'magic_number' is located.
