Avoid MMI in MIRPrinter

CodeGen: Avoid using MachineFunction::getMMI in MachineModuleSlotTracker (#100310)

2024-07-24T08:27:00+00:00

[IR] Don't include Module.h in Analysis.h (NFC) (#97023)

2024-06-28T12:30:47+00:00

Replace it with a forward declaration instead. Analysis.h is pulled in
by all passes, but not all passes need to access the module.

[CodeGen] Use default member initialization (NFC)

[MIRPrinter] Add machine metadata support.

2021-06-19T16:48:08+00:00

- Distinct metadata needs generating in the codegen to attach correct
  AAInfo on the loads/stores after lowering, merging, and other relevant
  transformations.
- This patch adds 'MachhineModuleSlotTracker' to help assign slot
  numbers to these newly generated unnamed metadata nodes.
- To help 'MachhineModuleSlotTracker' track machine metadata, the
  original 'SlotTracker' is rebased from 'AbstractSlotTrackerStorage',
  which provides basic interfaces to create/retrive metadata slots. In
  addition, once LLVM IR is processsed, additional hooks are also
  introduced to help collect machine metadata and assign them slot
  numbers.
- Finally, if there is any such machine metadata, 'MIRPrinter' outputs
  an additional 'machineMetadataNodes' field containing all the
  definition of those nodes.
