38a8d7fb2e Remove redundant 'inline' keywords from definitions 
Also add checks to t/t_dist_cppstyle

0c70a0dcbf Remove redundant 'virtual' keywords from overridden methods 
'virtual' is redundant when 'override' is present, so keep only
'override'.

Add t/t_dist_cppstyle.pl to check for this.

- Regroup and sort #include directives (like we used to, but automatic)
- Set AlwaysBreakTemplateDeclarations to true

2ba9eb4228 Speed up TSP sort implementation 
- More efficient comparison by pre-computing sorting keys.
- Remove work items in algorithms known to be redundant earlier.
  This greatly reduces data structure sizes.
- Use V3GraphVertex->user() for state tracking instead of unordered_map
  while both of these are constant time, they do add up.
- In `makeMinSpanningTree`, instead of batch inserting outgoing edges of
  each visited vertex into an ordered set, keep an ordered set of sorted
  vectors of edges. This reduces the size of the ordered set
  significantly (it is now O(V) rather than O(E), and as the subject
  graph is a complete graph, V ~ sqrt(E), so this is a significant gain).
- Use a vector + sorting in `perfectMatching` instead of an ordered set.
  This is faster on large working sets.

This yields 3.8x speedup on the variable order pass and overall 14%
verilation speed gain on a large design.
