Adds a CONSTANT_Integer_info or CONSTANT_Float_info to the constant pool of this symbol table.
Does nothing if the constant pool already contains a similar item.

@param tag one of {@link Symbol#CONSTANT_INTEGER_TAG} or {@link Symbol#CONSTANT_FLOAT_TAG}.
@param value an int or float.
@return a constant pool constant with the given tag and primitive values.
