Rename `-duplicate` to `-push-copy`. 
Co-Authored-By: whitequark <whitequark@whitequark.org>

whitequark e0def9e4d9 memory_map: add -attr option, to respect inference attributes. 
Before this commit, memory_map (which is always a part of a synth
script) would always pick up any $mem cell that was not processed
by a preceding pass and lower it down to $dff/$mux cells.
This is undesirable for two reasons:
  * If there is an explicit inference attribute set on a $mem cell,
    e.g. (* ram_block *), then it is arguably incorrect to map such
    a memory to $dff/$mux cells.
  * If memory_map tries to lower a memory that was intended to
    be mapped to a large BRAM, it often takes extraordinarily long
    time to finish, produces an extremely large log file, and outputs
    an unusable design.

After this commit, properly invoked memory_map will not map any
memory that has an explicit inference attribute specified, solving
the first issue, and alleviating the second. The default behavior
is not changed.

Marcin Kościelnicki f68985f997 deminout: prevent any constant assignment from demoting to input 
Before this patch,

```
module top(inout io);
assign io = 1'bx;
endmodule
```

would have the `io` pin demoted to input (same happens for `1'bz`,
but not for `1'b0` or `1'b1`), resulting in check failures later on.

Part of fix for #1841.

Rupert Swarbrick 044ca9dde4 Add support for SystemVerilog-style `define to Verilog frontend 
This patch should support things like

  `define foo(a, b = 3, c)   a+b+c

  `foo(1, ,2)

which will evaluate to 1+3+2. It also spots mistakes like

  `foo(1)

(the 3rd argument doesn't have a default value, so a call site is
required to set it).

Most of the patch is a simple parser for the format in preproc.cc, but
I've also taken the opportunity to wrap up the "name -> definition"
map in a type, rather than use multiple std::map's.

Since this type needs to be visible to code that touches defines, I've
pulled it (and the frontend_verilog_preproc declaration) out into a
new file at frontends/verilog/preproc.h and included that where
necessary.

Finally, the patch adds a few tests in tests/various to check that we
are parsing everything correctly.
