Eliminate this ugly hack. This was put back in when replaceAllUsesOf used
...
a different algorithm that was extremely inefficient for instructions with
many operands.
This reduces the time of this code snippet from .23s for 176.gcc to 0.03s
in a debug build, which speeds up total llvm-dis time just barely.
It's more of a code cleanup than a speedup.
