I've run testsuite several times since I have this patch on my local copy.
Note that when I implemented it the wrong way tests started to fail so it is
clearly having an effect on the generated code.
* include/bits/c++config [__OPTIMIZE__](__glibcxx_assert): Define as

using __builtin_unreachable.
Ok to commit ?
I see for instance in bits/regex_automaton.tcc:
__glibcxx_assert(__m.count(__ref._M_next) > 0);
where __m is a map, which does not look so well suited for a
__builtin_unreachable. Is it using the wrong macro?
