PATCH: use hashtab for pseudo op table

Well removing multiple implementations of the same thing is certainly good.

I guess the question comes down to - should bfd keep or re-implement its 
own hashtab code to be used everywhere in binutils or should the one 
from libiberty be used ?  Zack pointed out the performance penalty of 
using libiberty's code, and I would like to get a feel for whether this 
would be a serious hindrance to using it.
