348b4a7c12 IR: Expose the method 'getLocalSlot' in the module slot tracker. 
This commit publicly exposes the method 'getLocalSlot' in the
'ModuleSlotTracker' class.

This change is useful for MIR serialization, to serialize the unnamed basic
block and unnamed alloca references.

0d5d45176b CodeGen: Push the ModuleSlotTracker through Metadata 
For another 1% speedup on the testcase in PR23865, push the
`ModuleSlotTracker` through to metadata-related printing in
`MachineBasicBlock::print()`.

913c983bf7 CodeGen: Use a single SlotTracker in MachineFunction::print() 
Expose enough of the IR-level `SlotTracker` so that
`MachineFunction::print()` can use a single one for printing
`BasicBlock`s.  Next step would be to lift this through a few more APIs
so that we can make other print methods faster.

Fixes PR23865, changing the runtime of `llc -print-machineinstrs` from
many minutes (killed after 3 minutes, but it wasn't very close) to
13 seconds for a 502185 line dump.
