Optimize fixnum or s64 -> f64 conversions
* libguile/intrinsics.c (scm_bootstrap_intrinsics):
* libguile/intrinsics.h (SCM_FOR_ALL_VM_INTRINSICS): Add "inexact"
intrinsic.
* libguile/jit.c (compile_s64_to_f64): New compiler.
* libguile/vm-engine.c (s64->f64): New instruction.
* module/language/cps/effects-analysis.scm (heap-numbers-equal?):
* module/language/cps/reify-primitives.scm (compute-known-primitives):
* module/language/cps/slot-allocation.scm (compute-var-representations):
* module/language/cps/specialize-numbers.scm (fixnum->f64):
(specialize-operations):
* module/language/cps/type-fold.scm (scm->f64, inexact):
* module/language/cps/types.scm (inexact, s64->f64):
* module/language/tree-il/cps-primitives.scm (exact->inexact):
* module/language/tree-il/primitives.scm (*interesting-primitive-names*):
(*effect-free-primitives*):
* module/system/vm/assembler.scm: Recognize exact->inexact as a
primitive, and optimize it. Add compiler support for new "inexact"
and "s64->f64" primcalls.
