Added select flavour for ABS and NEG(ABS)
This patch can identify
ABS(X) ==> (X >s 0) ? X : -X and (X >s -1) ? X : -X
ABS(X) ==> (X <s 0) ? -X : X and (X <s 1) ? -X : X
NABS(X) ==> (X >s 0) ? -X : X and (X >s -1) ? -X : X
NABS(X) ==> (X <s 0) ? X : -X and (X <s 1) ? X : -X
and can transform
ABS(ABS(X)) -> ABS(X)
NABS(NABS(X)) -> NABS(X)
