Florian Hahn 5f746c8e27 Recommit rL305677: [CodeGen] Add generic MacroFusion pass
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.

This causes Windows buildbot failures do an ambiguous call.

Evandro Menezes 94edf02923 [CodeGen] Move MacroFusion to the target
This patch moves the class for scheduling adjacent instructions,
MacroFusion, to the target.

In AArch64, it also expands the fusion to all instructions pairs in a
scheduling block, beyond just among the predecessors of the branch at the
end.
