[llvm-dev] Mapping from IR instructions to MIR?

I'd like to use LLVM to generate a total mapping from IR instructions to
their lowered MIR counterpart(s), post all gMIR/legalization/ISel passes.
However, I'm having trouble figuring out whether this is currently
supported somewhere in the backend/has a known correct approach.
Does anybody know if this is something currently do-able within the
backend? I've run into a bit of a dead end with IRTranslator. There's also
a comment in LegalizerHelper.h that suggests the presence of configurable
"RecordInsertInstruction" functions, but I can't find any other
references to it.
