Manage lifetime of a slot tracker for printing IR.
Wrapper around the SlotTracker used internally by AsmWriter. This class allows callers to share the cost of incorporating the metadata in a module or a function.
If the IR changes from underneath ModuleSlotTracker, strings like "<badref>" will be printed, or, worse, the wrong slots entirely.

Construct a slot tracker from a module.
If M is nullptr
, uses a null slot tracker. Otherwise, initializes a slot tracker, and initializes all metadata slots. ShouldInitializeAllMetadata
defaults to true because this is expected to be shared between multiple callers, and otherwise MDNode references will not match up.

Return the slot number of the specified local value.
A function that defines this value should be incorporated prior to calling this method. Return -1 if the value is not in the function's SlotTracker.

Incorporate the given function.
Purge the currently incorporated function and incorporate F
. If F
is currently incorporated, this is a no-op.
