Yosys doesn't support libraries, so this provides the same behavior as
%m, as some other tools have opted to do.

Marcelina Kościelnicka 880df4c897 dfflegalize: Fix decision tree for adffe. 
When an adffe is being legalized, and is not natively supported,
prioritize unmapping to adff over converting to dffsre if dffsre is not
natively supported itself.

Fixes #2361.

Dan Ravensloft 1a07b330f8 intel_alm: Add multiply signedness to cells 
Quartus assumes unsigned multiplication by default, breaking signed
multiplies, so add an input signedness parameter to the MISTRAL_MUL*
cells to propagate to Quartus' <family>_mac cells.

whitequark 00e7dec7f5 Replace "ILANG" with "RTLIL" everywhere. 
The only difference between "RTLIL" and "ILANG" is that the latter is
the text representation of the former, as opposed to the in-memory
graph representation. This distinction serves no purpose but confuses
people: it is not obvious that the ILANG backend writes RTLIL graphs.

Passes `write_ilang` and `read_ilang` are provided as aliases to
`write_rtlil` and `read_rtlil` for compatibility.

whitequark 9f0892159e flatten, techmap: don't canonicalize tpl driven bits via sigmap. 
For connection `assign a = b;`, `sigmap(a)` returns `b`. This is
exactly the opposite of the desired canonicalization for driven bits.
Consider the following code:

    module foo(inout a, b);
      assign a = b;
    endmodule
    module bar(output c);
      foo f(c, 1'b0);
    endmodule

Before this commit, the inout ports would be swapped after flattening
(and cause a crash while attempting to drive a constant value).

This issue was introduced in 9f772eb9.

Fixes #2183.

Marcelina Kościelnicka 082cbcb4c7 synth_intel: Remove incomplete Arria 10 GX support. 
The techmap rules for this target do not work in the first place (note
lack of >2-input LUT mappings), and if proper support is ever added,
it'd be better placed in the synth_intel_alm backend.

Marcelina Kościelnicka 50d532f01c techmap/shift_shiftx: Remove the "shiftx2mux" special path. 
Our techmap rules for $shift and $shiftx cells contained a special path
that aimed to decompose the shift LSB-first instead of MSB-first in
select cases that come up in pmux lowering.  This path was needlessly
overcomplicated and contained bugs.

Instead of doing that, just switch over the main path to iterate
LSB-first (except for the specially-handled MSB for signed shifts
and overflow handling).  This also makes the code consistent with
shl/shr/sshl/sshr cells, which are already decomposed LSB-first.

Fixes #2346.

Xiretza 916028906a Ensure \A_SIGNED is never used with $shiftx 
It has no effect on the output ($shiftx doesn't perform any sign
extension whatsoever), so an attempt to use it should be caught early.
