* libguile/vm.h (struct scm_vm): Remove "time" and "clock" members. The time was bogusly measured, and the "clock" measured instructions retired, which is not a very useful measurement, and it was causing lots of memory accesses. Not that I have done a proper profile, though... (scm_vm_stats): Remove this procedure, which provided access to "time" and "clock". * libguile/vm.c: * libguile/vm-engine.h: * libguile/vm-engine.c: * libguile/vm-i-system.c: Adapt to scm_vm changes and scm_vm_stats removal. * module/system/repl/command.scm: * module/system/vm/vm.scm: Adapt to vm-stats removal by removing vm-stats from <repl>.
