Make use of extensions more explicit in libstdc++ tests
* testsuite/18_support/bad_exception/23591_thread-1.c: Add
-Wno-pedantic to dg-options.
* testsuite/20_util/align/2.cc: Use type as operand of alignof.
* testsuite/20_util/is_floating_point/value.cc: Add -Wno-pedantic
to dg-options.
* testsuite/20_util/specialized_algorithms/uninitialized_fill/32158.cc:
Remove extra semi-colon.
* testsuite/23_containers/array/tuple_interface/tuple_element.cc:
Always supply second argument to static_assert.
* testsuite/25_algorithms/lower_bound/no_operator_ne.cc: Remove extra
semi-colon.
* testsuite/26_numerics/complex/c99.cc: Add -Wno-pedantic to
dg-options.
* testsuite/26_numerics/complex/literals/values.cc: Likewise.
* testsuite/29_atomics/atomic/60695.cc: Likewise.
* testsuite/29_atomics/atomic/62259.cc: use __alignof__ instead of
alignof when operand is an object not a type.
* testsuite/decimal/ctor.cc: Add -Wno-pedantic to dg-options.
* testsuite/decimal/make-decimal.cc: Likewise.
* testsuite/experimental/type_traits/value.cc: Always supply second
argument to static_assert.
* testsuite/util/testsuite_common_types.h: Use __extension__ for
__int128 types.

Some small cleanups. These won't interfere with any testing of backports to gcc-6-branch before the release, so I'm committing them now. The first two remove some noise when using -Wsystem-headers: Avoid -Wsign-compare warnings in std::to_string() * include/ext/string_conversions.h (__stoa): Avoid -Wsign-compare warnings. Add attribute((unused)) in libstdc++ headers * include/bits/locale_facets.h (ctype::do_narrow): Add attribute to unused parameter. * include/bits/regex_automaton.h (_NFA::_M_insert_alt): Likewise. The other two remove some noise when running the testsuite with -Wpedantic, and tidy up some tests. Tested x86_64-linux, committed to trunk.
