  C library routines. See callclib().
ubyte `modregrm`(uint `m`, uint `r`, uint `rm`);
  Macros to ease generating code modregrm: generate mod reg r/m field modregxrm: reg could be R8..R15 modregrmx: rm could be R8..R15 modregxrmx: reg or rm could be R8..R15

  NEWREG change reg field of x to r genorreg: OR t,f
