Log:
[Driver] Make scudo compatible with -fsanitize-minimal-runtime
Summary:
This is the clang side of the change, there is a compiler-rt counterpart.
Scudo works with UBSan using `-fsanitize=scudo,integer` for example, and to do
so it embeds UBSan runtime. This makes it not compatible with the UBSan minimal
runtime, but this is something we want for production purposes.
The idea is to have a Scudo minimal runtime on the compiler-rt side that will
not embed UBSan. This is basically the runtime that is currently in use for
Fuchsia, without coverage, stacktraces or symbolization. With this, Scudo
becomes compatible with `-fsanitize-minimal-runtime`.
If this approach is suitable, I'll add the tests as well, otherwise I am open
to other options.

r335620 - [Driver] Do not add -lpthread & -lrt with -static-libsan on Android

Log:
[Driver] Do not add -lpthread & -lrt with -static-libsan on Android
Summary:
I am not sure anyone has tried to compile an application with sanitizers on
Android with `-static-libsan`, and a recent NDK, but it fails with:
```
.../i686-linux-android/bin/ld.gold: error: cannot find -lpthread
.../i686-linux-android/bin/ld.gold: error: cannot find -lrt
```
My understanding is that both are included in Bionic and as such are not needed,
and actually error out.
So remove the addition of those two in `linkSanitizerRuntimeDeps` when dealing
with Android, and update the tests.
I am unfamiliar with the evolution of the NDK and I am not sure if this has
always been the case or if this is somewhat of a recent evolution. I'll let
Android people chime in.

Log:
[Driver] Add PPC64 as supported for Scudo
Summary:
Scudo works on PPC64 as is, so mark the architecture as supported for it. This
will also require a change to config-ix.cmake on the compiler-rt side.
Update the tests accordingly.

Re: [clang] 80ed75e - Revert "[NFC] Fix typos"
Apologies.
As explained in another thread, this was a mistake of mine as I reverted 2
CLs instead of 1 (mine).
This was resolved with the original author.
My own CL ended up breaking some 32-bit builders.

LOG: [Clang][ASan] Correct AsanDtorKindToString to return non-void in default
case
Post D96572, a warning started showing up for me:
`clang/lib/Basic/Sanitizers.cpp:73:1: warning: control reaches end of non-void
function [-Wreturn-type]`
So this adds a default to the case to return invalid, which seems appropriate,
and appears to correct the issue.

r317337 - [Driver] Add Scudo as a possible -fsanitize= option
Author: cryptoad
Date: Fri Nov 3 10:04:13 2017
New Revision: 317337
URL: http://llvm.org/viewvc/llvm-project?rev=317337&view=rev
Log:
[Driver] Add Scudo as a possible -fsanitize= option
Summary:
This change adds Scudo as a possible Sanitizer option via -fsanitize=.
This allows for easier static & shared linking of the Scudo library, it allows
us to enforce PIE (otherwise the security of the allocator is moot), and check
for incompatible Sanitizers combo.
In its current form, Scudo is not compatible with any other Sanitizer, but the
plan is to make it work in conjunction with UBsan (-fsanitize=scudo,undefined),
which will require additional work outside of the scope of this change.

r291598 - [Driver] Add openSuse AArch64 Triple
Author: cryptoad

[Driver] Add openSuse AArch64 Triple
Summary:
openSuse has AArch64 support, with images running on the Raspberry Pi 3.
The libraries and headers live under the aarch64-suse-linux subdirectory,
which is currently not in the AArch64 triples list. Address this by adding
the corresponding string to AArch64Triples.
