Incorrect case folding in the LIKE operator

Changes

  1. foundin changed to: "3.10.0"
  2. icomment:
    The following (equivalent) queries return true, when the correct answer is false:
    
    <blockquote><verbatim>
    SELECT 'き' LIKE 'ね';
    SELECT char(0x304d) LIKE char(0x306d);
    </verbatim></blockquote>
    
    The culprit seems to be check-in [0a99a8c4facf] on [2015-12-30 14:06:22].  Case comparison is only looking at the lower 8 bytes of unicode values.
