scm->u64, scm->s64, scm->u64/truncate intrinsics
* libguile/intrinsics.c (scm_to_uint64_truncate): New intrinsic. (scm_bootstrap_intrinsics): Init new intrinsics. * libguile/intrinsics.h: Add scm->u64, scm->u64/truncate, and scm->s64 as intrinsics, with their corresponding types. * libguile/vm-engine.c (call-u64<-scm, call-s64<-scm): New intrinsic calling ops. (scm->u64, scm->s64, scm->u64/truncate): Disable opcodes. * module/language/cps/reify-primitives.scm (compute-known-primitives): Add intrinsics as new macroinstructions. * module/system/vm/assembler.scm: Declare new intrinsic assemblers.
