reducing branches.

for the new intrinsics.

(define-f64<-f64-f64-intrinsic): New helper.
Some components of this have been wired up for a while; this commit
finishes the compiler, runtime, and JIT support.
* libguile/intrinsics.h (SCM_FOR_ALL_VM_INTRINSICS):
* libguile/intrinsics.c (scm_bootstrap_intrinsics): Declare the new
intrinsics.
* libguile/jit.c (compile_call_f64_from_f64): Define code generators for
the new intrinsics.

handle it.

struct-set! as returning a value.
* module/language/tree-il/cps-primitives.scm (allocate-vector)

converter.
(allocate-vector): New converter.
* module/language/tree-il/cps-primitives.scm: New file,
replacing (language cps primitives). Lists known primitives and their
relation to Tree-IL explicitly, instead of assuming that any Tree-IL
primcall that shares a name with a bytecode instruction is a CPS
primcall.
* module/language/cps/verify.scm: Remove use of (language cps
primitives) and primcall arity checking. Would be nice to add this
back at some point.
