Update disassembler in NaCl binutils

We need newer version of disassembler for the validator tests (with
support for newer instructions like tzcnt) and till now we've used
complex dance which pulls new version of binutils and builds it when
needed. It's slow and error-prone.

Backport i386-dis.c from trunk instead (specifically from commit
from 27 Mar 2013, eb87183adc1fb9e7763a192d0d4577547f250ec9)
