 Description   

ABT currently doesn't support case-insensitive comparisons (it is described using a BinaryOp node, that has no space for specifying a collator). While waiting for QO to properly design it, store the pointer to the collator in a side map that SBEExpressionLowering can query to generate the correct SBE expression.
