04ea7c64e2 OptDiag: Use DiagnosticLocation in MachineOptimizationRemarks
DiagnosticInfo switched from DebugLoc to DiagnosticLocation in
r295519, update these subclasses to match.

75fdc3a2ae [CodeGen] Teach opt remarks how to print MI instructions.
This will be used with GISel opt remarks.

19925fc03b New OptimizationRemarkEmitter pass for MIR
This allows MIR passes to emit optimization remarks with the same level
of functionality that is available to IR passes.

It also hooks up the greedy register allocator to report spills.  This
allows for interesting use cases like increasing interleaving on a loop
until spilling of registers is observed.

I still need to experiment whether reporting every spill scales but this
demonstrates for now that the functionality works from llc
using -pass-remarks*=<pass>.
