vis algorithm improvement (2h42 -> 57m on ad_dm5) (#361) 
* vis algorithm improvement, new commandline option -targetchecks

* vis: only calculate num_expected_targetchecks if needed

Fixes a bit of performance regression when -targetchecks was added, when running
with -targetchecks 0, apparently due to the cost of all the std::popcount's.

gmsp3v2.bsp, 32 threads:
18s (brushbsp branch 9388d43b1c)
21.1s (vis algorithm improvement)
18.2s (this commit)

* vis: default targetchecks to 0.5

gmsp3v2.bsp vis, 32 threads: 18.2s -> 10.6s

Eric Wasylishen e9532346c7 vis: partly fix perf regression of Oct 2021 
- drops usage of winding_storage_hybrid
- makes pstack_t trivially default initializable again (like the C
  original)
- we weren't making use of the unlimited size of winding_storage_hybrid;
  the original vis already has an allowance for if a winding exceeds
  the fixed stack allocation size (24) and we were still applying that
  limit
