Internals: Make AstAssignW a procedural statement (#6280) (#6556) Initial idea was to remodel AssignW as Assign under Alway. Trying that uncovered some issues, the most difficult of them was that a delay attached to a continuous assignment behaves differently from a delay attached to a blocking assignment statement, so we need to keep the knowledge of which flavour an assignment was until V3Timing. So instead of removing AstAssignW, we always wrap it in an AstAlways, with a special `keyword()` type. This makes it into a proper procedural statement, which is almost equivalent to AstAssign, except for the case when they contain a delay. We still gain the benefits of #6280 and can simplify some code. Every AstNodeStmt should now be under an AstNodeProcedure - which we should rename to AstProcess, or an AstNodeFTask). As a result, V3Table can now handle AssignW for free. Also uncovered and fixed a bug in handling intra-assignment delays if a function is present on the RHS of an AssignW. There is more work to be done towards #6280, and potentially simplifying AssignW handing, but this is the minimal change required to tick it off the TODO list for #6280.

Improve Loop unrolling (#6480) (#6493) This patch implements #6480. All loop statements are represented using AstLoop and AstLoopTest. This necessitates rework of the loop unroller to handle loops of arbitrary form. To enable this, I have split the old unroller used for 'generate for' statements and moved it into V3Param, and subsequently rewrote V3Unroll to handle the new representation. V3Unroll can now unroll more complex loops, including with loop conditions containing multiple variable references or inlined functions. Handling the more generic code also requires some restrictions. If a loop contains any of the following, it cannot be unrolled: - A timing control that might suspend the loop - A non-inlined call to a non-pure function These constructs can change the values of variables in the loop, so are generally not safe to unroll if they are present. (We could still unroll if all the variables needed for unrolling are automatic, however we don't do that right now.) These restrictions seem ok in the benchmark suite, where the new unroller can generally unroll many more loops than before.

Internals: Make AstAssignW a procedural statement (#6280) (#6556) Initial idea was to remodel AssignW as Assign under Alway. Trying that uncovered some issues, the most difficult of them was that a delay attached to a continuous assignment behaves differently from a delay attached to a blocking assignment statement, so we need to keep the knowledge of which flavour an assignment was until V3Timing. So instead of removing AstAssignW, we always wrap it in an AstAlways, with a special `keyword()` type. This makes it into a proper procedural statement, which is almost equivalent to AstAssign, except for the case when they contain a delay. We still gain the benefits of #6280 and can simplify some code. Every AstNodeStmt should now be under an AstNodeProcedure - which we should rename to AstProcess, or an AstNodeFTask). As a result, V3Table can now handle AssignW for free. Also uncovered and fixed a bug in handling intra-assignment delays if a function is present on the RHS of an AssignW. There is more work to be done towards #6280, and potentially simplifying AssignW handing, but this is the minimal change required to tick it off the TODO list for #6280.

Improve Loop unrolling (#6480) (#6493) This patch implements #6480. All loop statements are represented using AstLoop and AstLoopTest. This necessitates rework of the loop unroller to handle loops of arbitrary form. To enable this, I have split the old unroller used for 'generate for' statements and moved it into V3Param, and subsequently rewrote V3Unroll to handle the new representation. V3Unroll can now unroll more complex loops, including with loop conditions containing multiple variable references or inlined functions. Handling the more generic code also requires some restrictions. If a loop contains any of the following, it cannot be unrolled: - A timing control that might suspend the loop - A non-inlined call to a non-pure function These constructs can change the values of variables in the loop, so are generally not safe to unroll if they are present. (We could still unroll if all the variables needed for unrolling are automatic, however we don't do that right now.) These restrictions seem ok in the benchmark suite, where the new unroller can generally unroll many more loops than before.

Improve Dfg type system (#6390) Added a mini type system for Dfg using DfgDataType to replace Dfg's use of AstNodeDType. This is much more restricted and represents only the types Dfg can handle in a canonical form. This will be needed when adding more support for unpacked arrays and maybe unpacked structs one day. Also added an internal type checker for DfgGraphs which encodes all the assumptions the code makes about type relationships in the graph. Run this in a few places with --debug-check. Fix resulting fallout.
