* module/scripts/compile.scm (%options): Resurrect -O option and make it follow GCC, more or less. The default is equivalent to -O2. * module/language/cps/compile-bytecode.scm (lower-cps): * module/language/cps/optimize.scm (optimize-higher-order-cps): Move split-rec to run unconditionally for now, as closure conversion fails without it. (define-optimizer): Only verify the result if we are debugging, to save time. (cps-default-optimization-options): New exported procedure. * module/language/tree-il/optimize.scm (tree-il-default-optimization-options): New exported procedure.
