[boost] [type_traits] please update is_convertible.hpp header in the RC branch

  The version of boost/type_traits/is_convertible.hpp in RC_1_34_0 branch
  has wrong conditionalization for HP-UX. It has been fixed in CVS HEAD --
  see below.

  This bug is causing two tests to fail on HP-UX/aCC6 in RC_1_34_0:

        . is_convertible_test from type_traits library
        . tr1_is_convertible_test from tr1 library

  I've confirmed, that with the HEAD version of the header, the two tests
  above pass (the type_traits library is, actually, becomes green) and
  using the HEAD version of the header in RC_1_34_0 testing does not
  introduce any regressions.

  Please, update boost/type_traits/is_convertible.hpp header in the RC branch 
with
  the version in CVS HEAD. As you can see from the attached differences,
  this bugfix is the only change in this header between CVS HEAD and the RC
  branch.

  Thanks,
    Boris
