[Builtins] Downgrade duplicate source file warning from a fatal error to
a warning.
This is a follow up to r375150 to unbreak the `clang-ppc64be-linux` bot.
The commit caused running the tests to fail due to
``` llvm-lit:
fatal: builtins_source_features contains duplicates:
This commit should be reverted once the build system bug for powerpc is

Reland "[lit] Synthesize artificial deadline"
We always want to use a deadline when calling `result.await`.  Let's
synthesize an artificial deadline (now plus one year) to simplify code
and do less busy waiting.
Thanks to Reid Kleckner for diagnosing that a deadline for of "positive
infinity" does not work with Python 3 anymore.  See commit:
I tested this patch with Python 2 and Python 3.

libhwasan initialisation include kernel syscall ABI relaxation
Summary: Until now AArch64 development has been on patched kernels that
have an always on relaxed syscall ABI where tagged pointers are
accepted. The patches that have gone into the mainline kernel rely on
each process opting in to this relaxed ABI.
This commit adds code to choose that ABI into __hwasan_init.
The idea has already been agreed with one of the hwasan developers
The patch ignores failures of `EINVAL` for Android, since there are
older versions of the Android kernel that don't require this `prctl` or
even have the relevant values.  Avoiding EINVAL will let the library run
on them.
I've tested this on an AArch64 VM running a kernel that requires this
prctl, having compiled both with clang and gcc.
