Bug#11758543 50756: BIGINT '100' MATCHES 1.001E2

Expressions of the form
      BIGINT_COL <compare> <non-integer constant>

      should be done either as decimal, or float.

      Currently however, such comparisons are done as int,
      which means that the constant may be truncated,
      and yield false positives/negatives for all queries
      where compare is '>' '<' '>=' '<=' '=' '!='.

      BIGINT_COL IN <list of contstants>
      and
      BIGINT_COL BETWEEN <constant> AND <constant>
      are also affected.
