Make IdString refcounts a hashtable containing only the nonzero refcounts
...
This saves space and doesn't cost very much since we hardly ever have nonzero refcounts any more.
It also allows for IdStrings with negative indexes, which we're going to add.

Switch the SigSpec packed representation to allow just a single chunk that's inline in the SigSpec.
...
Single-chunk SigSpecs are very common and this avoids a heap allocation. It also simplifies
some algorithms.

Instead of using packing and hashing to compute SigSpec ordering and equality, just use the width and chunkwise comparisons
...
This avoids having to pack and compute hashes, and generally results in a
simpler ordering.

Add CONST_FLAG_UNSIZED
...
In order to support unsized constants being used as parameters, the `const` struct needs to know if it is unsized (so that the parameter can be used to set the size).
Add unsized flag to param value serialization and rtlil back-/front-end.
Add cell params to `tests/rtlil/everything.v`.
