[Bug libstdc++/16612] New: empty basic_strings can't live in shared memory

[steve dot horn at gs dot com]

It appears that a basic_string created with a default constructor can't live in
shared memory because basic_string uses a static variable to hold a single empty
string (stored in _S_empty_rep_storage)
The memory associated with the empty string representation is local to the
process that created the string. Therefore one process can not access empty
strings created by a different process.

I would guess that basic_string should use it's allocator to acquire the memory
for the empty string representation.
