Detailed Description
SCEVUnknown - This means that we are dealing with an entirely unknown SCEV value, and only represent it as its LLVM Value. This is the "bottom" value for the analysis.

isSizeOf, isAlignOf, isOffsetOf - Test whether this is a special constant representing a type size, alignment, or field offset in a target-independent manner, and hasn't happened to have been folded with other operations into something unrecognizable. This is mainly only useful for pretty-printing and other situations where it isn't absolutely required for these to succeed.
