8c1999aac1 kernel/mem: Emit support for wide ports in packed mode. 
Since the packed cell doesn't actually support wide ports yet, we just
auto-narrow them on emit.  The future packed cell will add
RD_WIDE_CONTINUATION and WR_WIDE_CONTINUATION parameters so the
transform will be trivially reversible for proper serialization.

ff9713dd86 kernel/mem: Add model for wide ports. 
Such ports cannot actually be created or used yet, this just adds the
necessary plumbing in the helper.  Subsequent commits will gradually
add wide port support to various yosys passes.

95a39d3425 kernel/mem: Add priority_mask to model. 
This is going to be used to store arbitrary priority masks in the
future.  Right now, it is not supported by our cell library, so the
priority_mask is computed from port order on helper construction,
and discarded when emitted.  However, this allows us to already convert
helper-using passes to the new model.

There will soon be more (versioned) memory cells, so handle passes that

3421979f00 Change the type of current_module to Module 
The current_module global is needed so that genRTLIL has somewhere to
put cells and wires that it generates as it makes sense of expressions
that it sees. However, that doesn't actually need to be an AstModule:
the Module base class is enough.

This patch should cause no functional change, but the point is that
it's now possible to call genRTLIL with a module that isn't an
AstModule as "current_module". This will be needed for 'bind' support.

51ed4a7149 Use range-based for loop in AST::process 
No functional change: just get rid of the explicit iterator and
replace (*it)-> with child->. It's even the same number of characters,
but is hopefully a little easier to read.
