Manman Ren 90842427b2 Check whether a pointer is non-null (isKnownNonNull) in isKnownNonZero. ... This handles the case where we have an inbounds GEP with alloca as the pointer. This fixes the regression in PR12750 and rdar://13286434. Note that we can also fix this by handling some GEP cases in isKnownNonNull. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177321 91177308-0d34-0410-b5e6-96231b3b80d8		2013-03-18 21:23:25 +00:00
