libstdc++: Use more descriptive feature test macro
The out-of-class definitions of the static constants are redundant if
the __cpp_inline_variables feature is supported, so use that macro to
decide whether to define them or not.
libstdc++-v3/ChangeLog:
* include/bits/regex.h: Check __cpp_inline_variables instead of
__cplusplus.
