Unbox floor/ceiling and trigonometric functions where possible

Browse source 
* libguile/intrinsics.c (scm_atan1): New intrinsic, wrapping scm_atan.
  (scm_bootstrap_intrinsics): Add new intrinsics.
* libguile/intrinsics.h (scm_t_f64_from_f64_f64_intrinsic): New
  intrinsic type.
  (SCM_FOR_ALL_VM_INTRINSICS): Add intrinsics for floor, ceiling, sin,
  cos, tan, asin, acos, atan, and their unboxed counterparts.
* libguile/jit.c (sp_f64_operand): New helper.
  (compile_call_f64_from_f64, compile_call_f64_from_f64_f64): Call out
  to intrinsics.

* module/language/cps/reify-primitives.scm (compute-known-primitives):
  Add new intrinsics.
* module/language/cps/slot-allocation.scm (compute-var-representations):
  Add 'f64 slot types for the new unboxed intrinsics.
* module/language/cps/specialize-numbers.scm (specialize-operations):
  Support unboxing the new intrinsics.
* module/language/cps/types.scm: Define type inferrers for the new
  intrinsics.
* module/language/tree-il/cps-primitives.scm: Define CPS translations
  for the new intrinsics.
* module/language/tree-il/primitives.scm (*interesting-primitive-names*):
  (*effect-free-primitives*, atan): Define primitive resolvers.
