of the :LITTLE-ENDIAN feature. (Thanks to Luís Oliveira, lp#901661)
* enhancement: better disassembly of segment-prefixes on x86 and other
instruction prefixes (e.g. LOCK) on x86 and x86-64.
+ * optimization: FIND and POSITION on bit-vectors are orders of magnitude
+ faster (assuming KEY and TEST are not used, or are sufficiently trivial).
* optimization: SUBSEQ on vectors of unknown element type is substantially
faster. (lp#902537)
* optimization: specialized arrays with non-zero :INITIAL-ELEMENT can
