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.

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.

928fd40c2e Respect \A_SIGNED for $shift 
This reflects the behaviour of $shr/$shl, which sign-extend their A
operands to the size of their output, then do a logical shift (shift in
0-bits).

dc07ae9677 techmap: Add _TECHMAP_CELLNAME_ special parameter. 
This parameter will resolve to the name of the cell being mapped.  The
first user of this parameter will be synth_intel_alm's Quartus output,
which requires a unique (and preferably descriptive) name passed as
a cell parameter for the memory cells.

b0bee396a8 Add new builtin FF types 
The new types include:

- FFs with async reset and enable (`$adffe`, `$_DFFE_[NP][NP][01][NP]_`)
- FFs with sync reset (`$sdff`, `$_SDFF_[NP][NP][01]_`)
- FFs with sync reset and enable, reset priority (`$sdffs`, `$_SDFFE_[NP][NP][01][NP]_`)
- FFs with sync reset and enable, enable priority (`$sdffce`, `$_SDFFCE_[NP][NP][01][NP]_`)
- FFs with async reset, set, and enable (`$dffsre`, `$_DFFSRE_[NP][NP][NP][NP]_`)
- latches with reset or set (`$adlatch`, `$_DLATCH_[NP][NP][01]_`)

The new FF types are not actually used anywhere yet (this is left
for future commits).

c8c3c7af87 Use [[maybe_unused]] instead of YS_ATTRIBUTE(unused). 
[[maybe_unused]] is available since C++17, so this commit adds
a polyfill YS_MAYBE_UNUSED. Once we require C++17 we can drop it.

Add missing [[noreturn]] to log_file_error() 
Previously this was tagged only with YS_ATTRIBUTE(noreturn), but not
YS_NORETURN, so it got lost in #2173, resulting in warnings in
frontends/ast/simplify.cc:

frontends/ast/simplify.cc:267:1: warning: function declared 'noreturn' should not return [-Winvalid-noreturn]
}
^

7137f99658 kernel: guard include of signal.h more precisely. 
Upgrading to WASI SDK 11.0 caused the WASM build to fail because WASM
does not have signals. (Arguably Yosys was broken even before, it was
just broken silently.)

efa7424fb9 Restrict RTLIL::IdString to not contain whitespace or control chars. 
This is an existing invariant (most backends can't cope with these)
but one that was not checked or documented.
