changes in sbcl-2.3.0 relative to sbcl-2.2.11:
* enhancement: support for SLOT-VALUE and friends has been extended to
structure and condition instances.
* enhancement: the error message for invalid array index conditions is clearer.
(lp#1999337, reported by Hadrien Lacour)
* minor incompatible change: COMPILED-FUNCTION-P now returns false for
generic functions.
* minor incompatible change: the compiler emit STYLE-WARNING conditions for
FIND and POSITION where the item sought can never be present in the
sequence.
* optimization: support computing the remainder of a constant division by
multiplication.
* optimization: faster out of line float truncation routines.
* optimization: faster RATIONAL on 64-bit platforms.
* optimization: more compact testing of widetags on x86-64 and arm64.
* bug fix: type intersections of RATIONAL ranges with (NOT INTEGER) are
computed more consistently. (lp#1998008)
* bug fix: fix miscompilation of integer/fixnum comparisons where both
arguments are on the stack.
