Chris Lattner 317293b504 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. llvm-svn: 66404		2009-03-09 05:52:15 +00:00
