fix some dancing between bank size and RegisterBank enum values

in the process, fixed a decoding bug dealing with a0/a1/a2/a3 movs
(respected rex.b when rex.b should have been ignored)

this seems to maybe improve runtime ever so slightly, but this is really
meant as a cleanup commit more than anything.

   * discovered that `jna` and `jnb` are named what they are, instead of
     `jbe`/`jae` like their `setcc` an `cmovcc` counterparts. sorry. these will
     become `jbe` and `jae` in 2.x.
+* fix incorrect decode of a0/a1/a2/a3 mov register when rex.b is set
+  (rex.b would select register 8, but the register is unconditionally A)
 
 ## 1.1.5
 * fix several typos across crate docs - thank you Bruce! (aka github user waywardmonkeys)
