  Reland "[NewPM][CodeGen] Introduce CodeGenPassBuilder to help build codegen pipeline"

This reverts commit 94427af60c66ffea655a3084825c6c3a9deec1ad (relands
4646de5d75cfce3da4ddeffb6eb8e66e38238800 with fix).

Use "return std::move(AsmStreamer);" instead of "return AsmStreamer;" in
LVMTargetMachine::createMCStreamer. Unlike Clang, GCC seems having trouble
inserting a implicit lvalue->rvalue conversion.
