8c58fe4631 Use EBB layout order almost everywhere. 
The ebbs_numerically() function was a workaround for the unimplemented EBB layout
order.

d73c2c9dc0 Replace inst_order with Layout in Function. 
The Layout also handles EBB layout, so new append_ebb calls are necessary.

- Rewrite callers to use the public data member 'layout'.
- Implement Debug for Function in terms of the write module to avoid deriving
  it.

0ef0937016 More layout tests and bugfixes. 
Fix bugs in append methods. Linked lists are hard.

bd2945ab5e Implement instruction order. 
Each EBB has a linked list of instructions in layout order.

c76ba3a7f6 Add an EntityRef::wrap() method. 
This is the opposite of unwrap(). It converts the ad-hoc null references like
NO_EBB and NO_INST into the more standard Option<Ebb> type which unfortunately
takes twice as much space in data structures.

d3ed162bac Begin a layout module. 
The Layout data structure will keep track of the order of EBBs and their
instructions.

e874393419 Add an entity_map module. 
This supports the pattern of creating structs wrapping a u32 and using them as
indexes into a vector of entities. These entity references should implement the
EntityRef trait.

The EntityMap is a generic map from an EntityRef to some value type. It expects
densely indexed entities and uses a Vec to represent the mapping compactly.

8cb198b23c Delete the concept of 'local SSA form'. 
This was supposed to make verification fast, but WebAssembly is no longer in
this form since it's blocks can produce values.

Also, computing a flow graph and dominator tree is really fast anyway.
