Compute the and aggregate using a temporary uncompressed bitmap.

This function does not seek to match the "sizeinbits" attributes
of the input bitmaps.

@param bitmaps the source bitmaps
@param bufSize buffer size used during the computation in 64-bit
words (per input bitmap)
@return the or aggregate.
