[v3] libstdc++/17780

[Benjamin Kosnik <bkoz at redhat dot com>]

I'd like to put this already big patch in, and then put in the tuning
optimizations for it next. There are some obvious simplifications that
can be done in _M_reserve block, where the operator new calls can be
coalesced. That's later though.

Found two things while testing this.

1) rope is leaking memory, at least rope-7 in the threads test. This is
regardless of allocator used. Since rope is kind of in an iffy state
right now, I'm not going to worry about this at the moment. I should
probably bugzilla this.

2) I'm seeing destruction ordering differences between icc and g++ for
some of the static local bits. I'll put a smaller testcase in bugzilla
about this tomorrow after I get a chance to investigate this a bit more.
