SI-7102 Specialize isEmpty for bitsets
Currently bitsets use default isEmpty implementation inherited from
Set, which tests for "size == 0".
Calculating the size of a word in a bitmap requires summing through
all bits set, whereas testing for emptyness needs only one comparison
with zero.
This commit overrides the default implementation with the specialized
one looking for a non-zero word in this bitmap.
