Memory consumption is reduced during the compilation phase by keeping
the Core parse tree shared. In particular the file annotation takes a
lot of memory when not shared.

v3_kernel may produce unwanted and confusing warnings for code that
has been inlined with the new inliner (cerl_inline).  Consider this
code:

-compile(inline).

compute1(X) ->
    add(X, 0).

compute2(X, Y) ->
    add(X, Y).

add(1, 0) ->
    1;
add(1, Y) ->       %% "this clause cannot match..."
    1 + Y;
add(X, Y) ->
    X + Y.

v3_kernel warns because add/2 has been inlined into compute1/1 and only
the first clause in add/2 will match. But the other clauses are needed
when add/2 is inlined into compute2/2, so the user cannot do anything
to eliminate the warning (short of manually inlining add/2, defeating the
purpose of the 'inline' option).

The warning would be reasonable if compute2/2 didn't exist, but it would
be too complicated for the compiler to figure whether a warning make
sense or not.

Therefore, suppress all warnings generated by v3_kernel if cerl_inline
has been run.

* valgrind needs a lot of time

Funs must not be created in guards. The instruction for creating
a fun clobbers all X registers, which is a bad thing to do in
a guard.
