Misc optimizations to BinaryPlainBlockDecoder
Looking at a profile while running a YCSB read workload against a binary
built with clang, I noticed that BinaryPlainDecoder had done a really
poor job of inlining vector::push_back when building the offsets array.
This switches away from using a vector there and instead uses a simple
buffer/pointer view into the buffer. I also rearranged a bit of other
code and added PREDICT_FALSEs to try to get the code into a tighter
loop.
