This is a very poorly named feature. I think originally it meant to cover linux only, but the use of it in msan
seems to be about any aarch64 platform. Anyway, this change should be NFC on everything except Android.

The '-asan-use-private-alias’ option (disabled by default) option is currently only enabled for Linux and ELF, but it also works on Darwin and Mach-O. This option also fixes a known problem with LTO on Darwin (https://github.com/google/sanitizers/issues/647). This patch enables the support for Darwin (but still keeps it off by default) and adds the LTO test case.

The safestack overflow.c test is currently failing on an aarch64
buildbot with a segfault, but it is currently passing on other
configuration.
This patch silent the issue for now on aarch64 by setting to all
supported architectures the 'stable-runtime' configure and set
the test to requires it.

This patch adds runtime support for the Safe Stack protection to compiler-rt
(see http://reviews.llvm.org/D6094 for the detailed description of the
Safe Stack).
This patch is our implementation of the safe stack on top of compiler-rt. The
patch adds basic runtime support for the safe stack to compiler-rt that
manages unsafe stack allocation/deallocation for each thread.
Original patch by Volodymyr Kuznetsov and others at the Dependable Systems
Lab at EPFL; updates and upstreaming by myself.
