Summary: I had to make number of changes to the code and Makefile: * Add `make lib`, that will create static library without debug info. We need this to avoid growing binary too much. Currently it's 14MB. * Remove cpuinfo() function and use __SSE4_2__ macro. We actually used the macro as part of Fast_CRC32() function. As a result, I also accidentally fixed this issue: https://www.facebook.com/groups/rocksdb.dev/permalink/549700778461774/?stream_ref=2 * Remove __thread locals in OS_MACOSX Test Plan: `make lib PLATFORM=IOS` Reviewers: ljin, haobo, dhruba, sdong Reviewed By: haobo CC: leveldb Differential Revision: https://reviews.facebook.net/D17475
