When either instruction in a fused pair has no other dependency, besides on
the other instruction, make sure that other instructions do not get
scheduled between them. Additionally, avoid fusing an instruction more than
once along the same dependency chain.

This header includes CodeGen headers, and is not, itself, included by
any Target headers, so move it into CodeGen to match the layering of its
implementation.

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.
