I suggest you to use dynamic SQL as fieldnames number may very in future:

DECLARE @columns nvarchar(max),
        @sql nvarchar(max)

SELECT @columns = COALESCE(@columns,'') + ',' + QUOTENAME(c.fieldname)
FROM [Columns] c
ORDER BY c.cid

SELECT @sql = N'
    SELECT  v.[row],
    FROM [Values] v
    INNER JOIN [Columns] c
        ON v.cid = c.cid
    ) t
    MAX(fieldvalue) FOR fieldname IN ('+STUFF(@columns,1,1,'')+')
) pvt'

EXEC sp_executesql @sql

Will output:

row FirstName   LastName    Email               Phone
