cff1d6d4b5 Add a test to prove that hardened_malloc handles too-large-to-be-true allocations 
This pattern, used by https://github.com/kaist-hacking/HardsHeap,
uncovered bugs in other memory allocators.

4ccd6f16df always enable C++17 
The safe_flag check doesn't work properly for C++ flags with Clang so
this wasn't getting enabled despite the conditional compilation being
removed from the code, leading to breaking Clang builds.

a33d2ca97d Fix CPPFLAGS in test Makefile 
In particular, the _GNU_SOURCE feature test macro needs to be set in
order to correctly define mmap(2) flags such as MAP_ANONYMOUS.
Otherwise, compilation of some test files fails when CPPFLAGS is not
defined in the initial user environment, as Make then does not export it
from the root Makefile to the sub-make.

This is a more sensible way of handling an out-of-memory failure in this
edge case. It doesn't matter much in practice.
