1. Use fm's new matching features for x86 register matching. …

   Instead of using concrete register names, one can refer to a class of
   registers e.g. `r.8` is all 8-bit registers. To match a register name
   but ignore its value uses `r.8._`: to match a register name use `r.8.x`.
   Suffixes: must be unique (i.e. `r.8.x` and `r.8.y` must refer to
   different registers); and they refer to the "underlying" register (e.g.
   `r.8.x` and `r.64.x` might match `al` and `RAX` which is considered the
   same register, but will fail to match against `al` and `RBX`).
   
   To make this concrete these `assert`s all succeed:
   
   ```rust
   let fmm = fmatcher("r.8.x r.8.y r.64.x");
   assert!(fmm.matches("al bl rax").is_ok());
   assert!(fmm.matches("al al rax").is_err());
   assert!(fmm.matches("al bl rbx").is_err());
   assert!(fmm.matches("al bl eax").is_err());
   ```
