Juneyoung Lee f5677fe700 [ValueTracking] Let isGuaranteedNotToBeUndefOrPoison look into more constants/instructions 
Summary:
This patch helps isGuaranteedNotToBeUndefOrPoison look into more constants and instructions (bitcast/alloca/gep/fcmp).

To deal with bitcast, Depth is added to isGuaranteedNotToBeUndefOrPoison.

This patch is splitted from https://reviews.llvm.org/D75808.
