changes in sbcl-2.3.6 relative to sbcl-2.3.5:
  * platform support:
    ** restore building contribs on riscv; (lp#2002930)
    ** shorter constant-loading sequences on riscv;
    ** on OpenBSD, map the stack without executable permission (thanks to
       Sébastien Marie)
    ** Restore OpenBSD/arm64 for OpenBSD 7.3 (lp#2024003, reported by Robert
       Palm)
  * bug fix: AREF on multidimensional arrays with the wrong number of indices
    now signals an error.  (lp#2022327, reported by EU)
  * bug fix: the nature of NIL as both STRING and SEQUENCE is correctly handled
    in the compiler's handling of string functions.  (lp#2023118, reported by

    (lp#1824351)
  * optimization: better (the word-sized-type (ASH word-sized word-sized))
    when the result can overflow. For arm64 and x86-64.
  * optimization: better unoptimized calls to CEILING, FLOOR.
  * optimization: functions that involve coercing floats now cons less.
    For arm64 and x86-64.
  * optimization: array displacement to simple arrays is slightly faster.
