`mlir-tblgen` calls into the TableGen parser and then calls into a function based on the command line with the parsed records. In order to make it ingest a C++ file (or another kind of file), I have to intercept it in the main function:
Turn this
```c++
// Generator that prints records.
GenRegistration printRecords("print-records", "Print all records to stdout",
[](const RecordKeeper &records, raw_ostream &os) {
os << records;
return false;
});
int main(int argc, char **argv) { return MlirTblgenMain(argc, argv); }
```
Into this:
```c++
int main(int argc, char **argv) {
if (argv[1] == "shard-src-files") return shardSourceFiles(argc, argv)
return MlirTblgenMain(argc, argv);
}
```
