Add support for optimized unboxed abs and sqrt

Browse source 
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.
* libguile/vm-engine.c (call-f64<-f64): New instruction.
* module/language/cps/effects-analysis.scm:
* module/language/cps/reify-primitives.scm (compute-known-primitives):
* module/language/cps/slot-allocation.scm (compute-var-representations):
* module/language/cps/specialize-numbers.scm (specialize-operations):
* module/language/tree-il/cps-primitives.scm (abs):
* module/system/vm/assembler.scm (system, define-f64<-f64-intrinsic):
  (sqrt, abs, fsqrt, fabs):
* module/language/cps/types.scm (fsqrt, fabs): Add new f64<-f64
  primitives.
