Log:<br>
Turn the enum attributes DenseSet in AttrBuilder into a set of bits.<br>
<br>
Avoids malloc and is a lot denser. We lose iteration over target independent<br>
attributes, but that's a strange interface anyways and didn't have any users<br>
outside of AttrBuilder.</div></blockquote></div><br>One of the goals was to remove the arbitrary upper limit of 64 -- could you maybe use a BitVector so that we don't hit this later?</div></div>
