Fix a problem that instcombine would hit when dealing with unreachable code.

Because the instcombine has to scan the entire function when it starts up
to begin with, we might as well do it in DFO so we can nuke unreachable code.

Basic fix for PR#591; don't convert an fprintf() to an fwrite() if there
...
is a mismatch in their character type pointers (i.e. fprintf() prints an
array of ubytes while fwrite() takes an array of sbytes).
We can probably do better than this (such as casting the ubyte to an
sbyte).
