Siying Dong 58e1956d50 [Only for Performance Branch] A Hacky patch to lazily generate memtable key for prefix-hashed memtables. 
Summary:
For prefix mem tables, encoding mem table key may be unnecessary if the prefix doesn't have any key. This patch is a little bit hacky but I want to try out the performance gain of removing this lazy initialization.

In longer term, we might want to revisit the way we abstract mem tables implementations.

Test Plan: make all check
