ea79e16bab xilinx_dffopt: Don't crash on missing IS_*_INVERTED. 
The presence of IS_*_INVERTED on FD* cells follows Vivado, which
apparently has been decided by a dice roll.  Just assume false if the
parameter doesn't exist.

Fixes #2559.

01626e6746 opt_share: Fix X and CO signal width for shifted $alu in opt_share. 
These need to be the same length as actual Y, not visible part of Y.

1419c8761c Fix constants bound to redeclared function args 
The changes in #2476 ensured that function inputs like `input x;`
retained their single-bit size when instantiated with a constant
argument and turned into a localparam. That change did not handle the
possibility for an input to be redeclared later on with an explicit
width, such as `integer x;`.

0d8e5d965f Sign extend port connections where necessary 
- Signed cell outputs are sign extended when bound to larger wires
- Signed connections are sign extended when bound to larger cell inputs
- Sign extension is performed in hierarchy and flatten phases
- genrtlil indirects signed constants through signed wires
- Other phases producing RTLIL may need to be updated to preserve
  signedness information
- Resolves #1418
- Resolves #2265

d3b6b7fe98 xilinx: Fix attributes_test.ys 
This test pretty much passes by accident — the `prep` command runs
memory_collect without memory_dff first, which prevents merging read
register into the memory, and thus blocks block RAM inference for a
reason completely unrelated to the attribute.

The attribute setting didn't actually work because it was set on the
containing module instead of the actual memory.

eb76d35e80 memory_dff: Fix needlessly duplicating enable bits. 
When the register being merged into the EN signal happens to be a $sdff,
the current code creates a new $mux for every bit, even if they happen
to be identical (as is usually the case), preventing proper grouping
further down the flow.  Fix this by adding a simple cache.

Fixes #2409.

7670a89e1f opt_clean: Better memory handling. 
Previously, `$memwr` and `$meminit` cells were always preserved (along
with the memory itself).  With this change, they are instead part of the
main cell mark-and-sweep pass: a memory (and its `$meminit` and `$memwr`
cells) is only preserved iff any associated `$memrd` cell needs to be
preserved.

* xilinx: eliminate SCCs from DSP48E1 model

* xilinx: add SCC test for DSP48E1

* Update techlibs/xilinx/cells_sim.v

* xilinx: Gate DSP48E1 being a whitebox behind ALLOW_WHITEBOX_DSP48E1

Have a test that checks it works through ABC9 when enabled
