ECR #304775 - First batch of build fixes for clang.
Fixes hard source errors and a handful of simple warnings, but leaves most other warnings for later. Other errors not fixed here are from adding compile flags that are not understood.

ECR #333753 - TargetMachine is created not only for codegen, but for optimizer as well
This is to provide target specific optimizations in the intermediate optimizer.
LLVM 3.6 provides TargetTransformInfo for this purpose which requires TargetMachine.
No correctness issues will occur if TargetInfo is not created, but optmizations will target generic machine.
Testing: smoke, precheckin
