53ba3cf718 Fix the truth table for $_SR_* cells. 
This brings the documented behavior for these cells in line with
$_DFFSR_* and $_DLATCHSR_*, which is that R has priority over S.
The models were already reflecting that behavior.

Also get rid of sim-synth mismatch in the models while we're at it.

38a0c30d65 Get rid of dffsr2dff. 
This pass is a proper subset of opt_rmdff, which is called by opt, which
is called by every synth flow in the coarse part.  Thus, it never
actually does anything and can be safely removed.

2106f78bb1 ast/simplify: improve enum handling. 
Before this commit, enum values were serialized as attributes of form
  \enum_<width>_<value>
where <value> was a decimal signed integer.

This has multiple drawbacks:
  * Enums with large values would be hard to process for downstream
    tooling that cannot parse arbitrary precision decimals. (In fact
    Yosys also did not correctly process enums with large values,
    and would overflow `int`.)
  * Enum value attributes were not confined to their own namespace,
    making it harder for downstream tooling to enumerate all such
    attributes, as opposed to looking up any specific value.
  * Enum values could not include x or z, which are explicitly
    permitted in the SystemVerilog standard.

After this commit, enum values are serialized as attributes of form
  \enum_value_<value>
where <value> is a bit sequence of the appropriate width.

2e37e62e6b synth_intel_alm: alternative synthesis for Intel FPGAs 
By operating at a layer of abstraction over the rather clumsy Intel primitives,
we can avoid special hacks like `dffinit -highlow` in favour of simple techmapping.

This also makes the primitives much easier to manipulate, and more descriptive
(no more cyclonev_lcell_comb to mean anything from a LUT2 to a LUT6).

5c6e681673 Use static constexpr instead of static const where possible. 
In particular inside class declarations, a static const
assignment is technically not a definition, while constexpr is.

6c16fd760b opt_expr: Add more $alu optimizations. 
Detect the places in the $alu where the carry bit is constant (due to
const A[i] == B[i] ^ BI) and split it into smaller $alu at these points.

Also, make the existing const-carry detection for low bits more generic
(now handles cases where both BI and CI are constant, but not equal to
one another).

Fixes #1912.
