ee18fb4aac libstdc++: Fix x86 thread-safe one-time-construction implementation.
The root of the problem is that the existing implementation is based on the
ARM C++ ABI, which mandates a different guard variable layout than the
Itanium/x86 C++ one.

This patch modifies the implementation in a way that satisfies both ABIs (and
doesn't require changing the toolchains).

7c72513bfa libstdc++: make operator new call abort on failure.
This change ensures that operator new will call abort() in case
of memory allocation failure. Note that due to our usage of memory
overcommit, this can only happen under very rare circumstances
(i.e. trying to allocate memory larger than the larger free range
of virtual address space, or when memory is corrutped in various
ways).
