RFR: 8301992: Embed SymbolTable CHT node

Tue Feb 14 17:38:33 UTC 2023

Please review this patch for embedding the Symbol inside a ConcurrentHashTable Node instead of having a pointer to a Symbol. This eliminates malloc/free for each Symbol.

This patch is co-authored by @robehn.

Passed tiers 1 - 4 testing.
