The rest of FixedBitVector's code relies on this relationship.  So, let's make it explicit.

Also, fixed a bug in BitMap's API tests: testBitmapConcurrentTestAndSet() and
testBitmapConcurrentTestAndClear() were exercising testAndSet() and testAndClear()
respectively instead of their concurrent versions.  This is now fixed.  This issue was
originally found by Yijia Huang in https://bugs.webkit.org/show_bug.cgi?id=250847.
