The introduction of the empty __pair_base base class for PR 86751
changed the layout of std::pair<std::pair<...>, ...>. The outer pair and
its first member both have a base class of the same type, which cannot
exist at the same address. This causes the first member to be at a
non-zero offset.

The solution is to make the base class depend on the template
parameters, so that each pair type has a different base class type,
which allows the base classes of the outer pair and its first member to
have the same address.

GCC ICEs under -mslow-flash-data and -mword-relocations because there
is no way to load an address, both literal pools and MOVW/MOVT being
forbidden. This patch gives an error message when both options are
specified by the user and adds the according dg-skip-if directives for
tests that use either of these options. It also explicitely set the
option when in PIC mode as per documentation rather than always check
for target_word_relocation together with flag_pic.
