Robert O'Callahan 261a0ae9e1 Implement at() methods on SigSpec so that SigSpec::bits().at() continues to work as it did 
Fixes a regression caused by commit 745222fa3b, which caused some
third-party code to fail to build, e.g.:
5d7aa035c6/lib/Transforms/YosysOptimizer/RTLILImporter.cpp (L229)

Robert O'Callahan b0e2d75dbe 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.

Robert O'Callahan 870ae18a2d 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.

Robert O'Callahan a69d48dd19 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.
