- Domains: The new LoopKernelDomains class now holds on to some derived variables that are incrementally updated to avoid recomputation during every instantitation.
- Inames: Stores inames in a sparse-sense.
- Depends on make LoopKernel.__init__ leaner #293

This is done by adding attribute-specific copies so that heavy operations in LoopKernel.__init__ are invoked only when necessary
* Provides better performance via taking into account incremental updates * Adds :mod:`pyrsistent` as a dep.
* dict would be a dense data structure that would require lead costly LoopKernel copies.
* pyrsistent.PClass doesn't play well with pylint
* adds pyrsistent to list of intersphinx mappings
* LoopKernelDomains.swap(..) exits early if the obtained domain is identical
- there was really no good reason why this was present in the first place - allowing this is a GOOD idea as it allows to have more flexibility in defining fine-grained domains
… copy in all cases

This PR started depending on #372 in that the current code-generation implementation starts doing wonky updates to the domain which doesn't retain certain assumptions this branch makes like each iname belongs to exactly one home domain. I'm closing this in favor of that. The downside is that #372 starts increasing in volume, but there's no good way to keep them separate. |
