The buildX naming convention originated when the CIRGen implementation was planned to be substantially different from original CodeGen. CIRGen is now a much closer adaption of CodeGen, and the emitX to buildX renaming just makes things more confusing, since CodeGen also has some helper functions whose names start with build or Build, so it's not immediately clear which CodeGen function corresponds to a CIRGen buildX function. Rename the buildX functions back to emitX to fix this.
