replacing the Epattern constructor. Patterns may now only
occur at their rightful place, on the left of an assignment.

Add Ewhen to the minils ast, And clocking of iterators.
...
Ewhen is now the only case of possible recursion for minils exps.
This add was motivated by equations like :
(y,z) = f(x) when c
This equation to be correctly normalized in minils before needed :
y',z' = f(x)
y = y' when c
z = z' when c
But this new variables where needless since the final translation of when c
is the identity.

Currently not implemented in hepts: array types.
Usage: to simulate the node Modulename.f:

really fix normalize_mem.
...
in the old fix was missing the renaming, and there was wrong equations
order :
f () returns x
[here rename x by mem_x]
mem_x = fby ...
x = mem_x
so the simplest was :
f () returns out_x
var x;
[ nothing to do]
out_x = x
x = fby ...
pay attention to the order of equations since we are after the
scheduling..
probably it should be done before the scheduling anyway ?
