- define-instruction-vops.lisp: only declare foldable on defknown when
the underlying instruction set is available on the host CPU.
- define-scalar-casts.lisp: gate sb-c:foldable on instruction-set-available-p.
- define-associatives.lisp, define-reducers.lisp, define-comparisons.lisp,
define-unequals.lisp, define-ifs.lisp: fallback to define-missing-instruction
when the instruction set is unavailable on the host. This prevents compile-time
constant folding from attempting to evaluate vector constructors or instructions
on host CPUs lacking the requisite instruction set extensions.
