Eli Friedman 054ddf799b A bunch of misc fixes to SCCPSolver::ResolvedUndefsIn, including a fix to stop
making random bad assumptions about instructions which are not explicitly listed.  

Includes fix for rdar://9956541, a version of "undef ^ undef should return
0 because it's easier than arguing with users".
