[ValueTracking] Add support for X*X self-multiplication
D108992 added KnownBits handling for 'Quadratic Reciprocity' self-multiplication patterns (bit[1] == 0), which can be used for non-undef values (poison is OK).
This patch adds noundef selfmultiply handling to value tracking so demanded bits patterns can make use of it.
