Geza Lore 1106e89c84 Optimize random initialization 
Fetching a thread-local is relatively expensive. Random initializing
wides used to do it once or twice per word, and on short runs for
large designs can be noticeably expensive, so fetch once per variable
instead. Also remove unused VL_RAND_RESET_{Q,W} functions.

Optimize module inlining heuristic (#7837) 
Rewrite module inlining decision to be based on a bipartite Module/Cell
graph, similar to V3InlineCFuncs. Preserved all old heuristics, but
added 2 new ones:

- If a module, and all the sub-hierarchy below it, is less than 10% the
  total flattened size of the design, then flatten the contents of that
  module (but the module itself is not necessarily inlined).

- If the flattened size of all instances of a module is less than 20% of
  the total flattened size of the design, then inline all instances of
  that module.

These are both relative to the total size of the design, so they
auto-scale with complexity. The net effect is that large shared
instances are preserved, but their contents are flattened out. E.g. in a
multi-core CPU this would keep the cores non-inlined but flatten out
most everything else. This still enables V3Combining and sharing those
later, but avoids potentially big overheads e.g. with small widely used
library modules.

Empirically this yields less generated C++ than the previous version
(due to removing lots of small functions), and can improve performance
10-20% while still having meaningful combining relative to the size of
the design.
