Chris Lattner f231c07228 Make the code generator rip of dead constant expr uses before deciding ...

whether a global is dead or not.  This should fix PR3749 - linker adds 
spurious use to appending globals.  I can't reasonably add a testcase
for this, because the bc writer/reader strip dead constant users.
