nit - could you have two separate headings and remove the extra comments: 

// Casts accumulator and stores result in accumulator.
BytecodeArrayBuilder& CastAccumulatorToBoolean();
BytecodeArrayBuilder& CastAccumulatorToJSObject();

// Casts accumulator and stores result in register out.
BytecodeArrayBuilder& CastAccumulatorToName(Register out);
BytecodeArrayBuilder& CastAccumulatorToNumber(Register out);

Done.

+  BytecodeArrayBuilder& CastAccumulatorToName(Register out);
   // Does not update the accumulator but stores to |out| instead.
   BytecodeArrayBuilder& CastAccumulatorToNumber(Register out);
