  [CostModel][TTI] Replace BAD_ICMP_PREDICATE with ICMP_SGT/UGT for generic abs/min/max cost expansion

Split off ABS cost handling from MIN/MAX and use explicit predicates for each

Our generic expansion of ABS doesn't use NEG+CMP+SELECT any more (its now ASHR+ADD+XOR) so this needs to be updated.
