r355343 was landed and was reverted in r355363 due to build breakage. This patch adds Linux/Windows support on top of r355343. In this patch, Darwin should be working with testing case. Linux should be working, I will enable the testing case in a follwup diff. Windows/Other should be building. Correct implementation for Other platforms will be added. Thanks David for reviewing the original diff, helping me with issues on Linux, and giving suggestions for adding support for Other platforms. llvm-svn: 355701
