Separate from ulimit, 32 bit AIX processes have the concept of memory
segments. By default, AIX devotes one 256MB segment to the data
section of an executable. Some libstdc++ testcases allocate more than
that amount of memory. Instead of individually fixing tests, this
patch always adds the AIX linker option to allocate two segments for
data, fixing a number of wchar testcases.

* testsuite/lib/libstdc++.exp (DEFAULT_CXXFLAGS): Add -Wl,-bmaxdata on AIX.
* testsuite/23_containers/vector/profile/vector.cc: Remove
dg-additional-options.
