Use llvm::make_unique to avoid ambiguity with MSVC. This patch adds a generic MacroFusion pass, that is used on X86 and AArch64, which both define target-specific shouldScheduleAdjacent functions. This generic pass should make it easier for other targets to implement macro fusion and I intend to add macro fusion for ARM shortly.
