This fixes an error when a constant is being loaded into a flag. The constants associated with a flag value have their size set to zero. That causes the mask for the constant value to be all zeros. Due to that, getting the value of a zero sized constant will always return 0 even if it should be 1. This commit special cases the size of zero to create a mask of 1 which will correctly mask off the lowest byte and return that as the constant.
