Rupert Swarbrick ee2b5b7ed1 Generate an RTLIL representation of bind constructs 
This code now takes the AST nodes of type AST_BIND and generates a
representation in the RTLIL for them.

This is a little tricky, because a binding of the form:

    bind baz foo_t foo_i (.arg (1 + bar));

means "make an instance of foo_t called foo_i, instantiate it inside
baz and connect the port arg to the result of the expression 1+bar".
Of course, 1+bar needs a cell for the addition. Where should that cell
live?

With this patch, the Binding structure that represents the construct
is itself an AST::AstModule module. This lets us put the adder cell
inside it. We'll pull the contents out and plonk them into 'baz' when
we actually do the binding operation as part of the hierarchy pass.

Of course, we don't want RTLIL::Binding to contain an
AST::AstModule (since kernel code shouldn't depend on a frontend), so
we define RTLIL::Binding as an abstract base class and put the
AST-specific code into an AST::Binding subclass. This is analogous to
the AST::AstModule class.

Brett Witherspoon 979053855c sv: improve support for wire and var with user-defined types 
- User-defined types must be data types. Using a net type (e.g. wire) is
  a syntax error.
- User-defined types without a net type are always variables (i.e.
  logic).
- Nets and variables can now be explicitly declared using user-defined
  types:

    typedef logic [1:0] W;
    wire W w;

    typedef logic [1:0] V;
    var V v;

Fixes #2846

Marcelina Kościelnicka b98376884e test/arch/{ecp5,ice40}/memories.ys: Use read_verilog -defer. 
These parts keep rereading a Verilog module, then using chparam
to test it with various parameter combinations.  Since the default
parameters are on the large side, this spends a lot of time
needlessly elaborating the default parametrization that will then
be discarded.  Fix it with -deref and manual hierarchy call.

Shaves 30s off the test time on my machine.

Marcelina Kościelnicka d25b9088c8 Refactor common parts of SAT-using optimizations into a helper. 
This also aligns the functionality:

- in all cases, the onehot attribute is used to create appropriate
  constraints (previously, opt_dff didn't do it at all, and share
  created one-hot constraints based on $pmux presence alone, which
  is unsound)
- in all cases, shift and mul/div/pow cells are now skipped when
  importing the SAT problem (previously only memory_share did this)
  — this avoids creating clauses for hard cells that are unlikely
  to help with proving the UNSATness needed for optimization

Zachary Snow c016f6a423 proc_rmdead: use explicit pattern set when there are no wildcards 
If width of a case expression was large, explicit patterns could cause
the existing logic to take an extremely long time, or exhaust the
maximum size of the underlying set. For cases where all of the patterns
are fully defined and there are no constants in the case expression,
this change uses a simple set to track which patterns have been seen.

Marcelina Kościelnicka 436d42c00c opt_expr: Propagate constants to port connections. 
This adds one simple piece of functionality to opt_expr: when a cell
port is connected to a fully-constant signal (as determined by sigmap),
the port is reconnected directly to the constant value.  This is just
enough optimization to fix the "non-constant $meminit input" problem
without requiring a full opt_clean or a separate pass.
