4a25e7442a feat(kernel/expr): add optional expression caching (aka "partial" hash-consing) 
We do not enforce full hash-consing because we would need to synchronize
the access to the hashtable/cache.

1b4c9f63ce perf(kernel/environment): improve is_descendant performance, optimize for the common case: the is_descendant tree is huge but has few deep branches 
This is an important optimization for module.cpp. The benchmark tests/lua/slow/mod2.lua is a good example where the cost of is_descendant was neutralizing the benefit of the replace method.
