Operations on 8-bit and 12-bit operands shuffle args into range
* module/language/cps/slot-allocation.scm (allocate-slots): Avoid allocating locals in the range [253,255]. * module/system/vm/assembler.scm: List exports explicitly. For operations with limited-range operands, export wrapper assemblers that handle shuffling their operands into and out of their range. (define-assembler): Get rid of enclosing begin. (shuffling-assembler, define-shuffling-assembler): New helpers to define shuffling wrapper assemblers. (emit-mov*, emit-receive*): New functions. (shuffle-up-args): New helper. (standard-prelude, opt-prelude, kw-prelude): Call shuffle-up-args after finishing. * test-suite/tests/compiler.test ("limits"): Add test cases.
