                        bigint' fails on windows.
    
    Visual Studio does not take into account some x86 hardware limitations
    which leads to incorrect results when converting large DOUBLE values
    to BIGINT UNSIGNED ones.
    
    Fixed by adding a workaround for double->ulonglong conversion on
    Windows.
    
    
    include/config-win.h:
      Added double2ulonglong(double) function implementing a workaround for
      broken double->ulonglong conversion on Windows/x86.
    include/my_global.h:
      Define double2ulonglong() as a simple typecast for anything but
      Windows.
    mysql-test/r/type_float.result:
      Added a test case for bug #27483.
    mysql-test/t/type_float.test:
      Added a test case for bug #27483.
