    openmp: Copy DECL_LANG_SPECIFIC and DECL_LANG_FLAG_? to tree-nested decl
copy [PR114825]

    tree-nested.cc creates in 2 spots artificial VAR_DECLs, one of them is =
used
    both for debug info and OpenMP/OpenACC lowering purposes, the other sol=
ely
for
    OpenMP/OpenACC lowering purposes.
    When the decls are used in OpenMP/OpenACC lowering, the OMP langhooks
(mostly
    Fortran, C just a little and C++ doesn't have nested functions) then
inspect
    the flags on the vars and based on that decide how to lower the
corresponding
    clauses.

    Unfortunately we weren't copying DECL_LANG_SPECIFIC and DECL_LANG_FLAG_=
?,
so
    the langhooks made decisions on the default flags on those instead.
    As the original decl isn't necessarily a VAR_DECL, could be e.g. PARM_D=
ECL,
    using copy_node wouldn't work properly, so this patch just copies those
    flags in addition to other flags it was copying already.  And I've remo=
ved
    code duplication by introducing a helper function which does copying co=
mmon
    to both uses.
