sdong e9ed28f9c8 PlainTableBuilder::Add() to use local char array instead of reused std::string as tmp buffer 
Summary: Our profile shows that in one of the applications, 5% of the CPU costs of PlainTableBuilder::Add() are spent on std::string stacks. By this simple change, we avoid this global reusable string. Also, we avoid another call of file appending, which probably gives another 2%.

Test Plan: make all check
