mescc: Support 64-bit immediates.
* module/mescc/M1.scm (hex2:address8, hex2:immediate8): New function. (info->M1): Support 64-bit. * module/mescc/compile.scm (convert-r0): FIXME! * module/mescc/x86_64/as.scm (x86_64:value->r, x86_64:r->local, x86_64:label->arg, x86_64:label->r, x86_64:r+value, x86_64:r-cmp-value, x86_64:r-long-mem-add, x86_64:r-and): Support 64-bit immediates. * lib/x86_64-mes/x86_64.M1: Likewise. * scaffold/tests/17-compare-unsigned-char-le.c: Test it. * scaffold/tests/17-compare-unsigned-short-le.c: Test it. * build-aux/check-mescc.sh (tests): Run them.
