Take into account the number of locations taken up by a uniform

When assigning uniform locations it now takes into account the number
of locations occupied by the type. For uniforms, all types except
arrays and structs take up one location. For arrays the base location
count is multiplied by the array dimensions and for structs it is the
sum of the locations of each member.
