libstdc++: [_GLIBCXX_INLINE_VERSION] Fix tests failures
Adapt testsuite v3_target_compile to strip version namespace from compiler
output so that dg-error and dg-warning directives do not need to consider
it.
libstdc++-v3/ChangeLog:
* testsuite/lib/libstdc++.exp (v3_target_compile): Strip version
namespace
from compiler output.
* testsuite/20_util/function/cons/70692.cc: Remove now useless __8
namespace
pattern.
* testsuite/23_containers/map/48101_neg.cc: Likewise.
* testsuite/23_containers/multimap/48101_neg.cc: Likewise.
