Summary:
This patch (on top of the previous two (https://reviews.llvm.org/D40898 and
https://reviews.llvm.org/D40899) complete the compiler-rt side of the the Solaris
sanitizer port.
It contains the following sets of changes:
* For the time being, the port is for 32-bit x86 only, so reject the various tests on
x86_64.
* When compiling as C++, <setjmp.h> resp. <iso/setjmp_iso.h> only declares
_setjmp and _longjmp inside namespace std.
* MAP_FILE is a Windows feature. While e.g. Linux <sys/mman.h> provides a
no-op compat define, Solaris does not.
* test/asan/TestCases/Posix/coverage.cc was initially failing like this:
/vol/gcc/src/llvm/llvm/local/projects/compiler-rt/lib/sanitizer_common/scripts/sancov.py: 4 files merged; 2 PCs total
rm: cannot remove '/var/gcc/llvm/local/projects/compiler-rt/test/asan/I386SunOSConfig/TestCases/Posix/Output/coverage': Invalid argument
Further digging revealed that the rm was trying to remove the running test's working
directory which failed as observed. cd'ing out of the dir before let the test pass.
* Two tests needed a declaration of alloca. I've now copied the existing code from
test/asan/TestCases/alloca_constant_size.cc, but it may be more profitable and
maintainable to have a common testsuite header where such code is collected.
* Similarly, Solaris' printf %p format doesn't include the leading 0x.
* In test/asan/TestCases/malloc-no-intercept.c, I had to undef __EXTENSIONS__
(predefined by clang for no apparent reason) to avoid conflicting declarations
for memalign.
* test/ubsan/TestCases/Float/cast-overflow.cpp has different platform dependent
ways to define BYTE_ORDER and friends. Why not just use __BYTE_ORDER__ and
friends as predefined by clang and gcc?

Summary:
As discussed in https://github.com/google/oss-fuzz/issues/933,
it would be really awesome to be able to use ThinLTO for fuzzing.
However, as @kcc has pointed out, it is currently undefined (untested)
whether the sanitizers actually function properly with LLD and/or LTO.
This patch is inspired by the cfi test, which already do test with LTO
(and/or LLD), since LTO is required for CFI to function.
I started with UBSan, because it's cmakelists / lit.* files appeared
to be the cleanest. This patch adds the infrastructure to easily add
LLD and/or LTO sub-variants of the existing lit test configurations.
Also, this patch adds the LLD flavor, that explicitly does use LLD to link.
The check-ubsan does pass on my machine. And to minimize the [initial]
potential buildbot breakage i have put some restrictions on this flavour.
Please review carefully, i have not worked with lit/sanitizer tests before.
The original attempt, r319525 was reverted in r319526 due
to the failures in compiler-rt standalone builds.

append() isn't available with some cmake versions, so I need to use a
different construct. I missed this case in r315144.

As a follow-up to r315142, this makes it possible to use ubsan with a
static runtime on Darwin. I've also added a new StandaloneStatic testing

Summary:
Enable check-cfi and check-ubsan on Android.
Check-ubsan includes standalone and ubsan+asan, but not tsan or msan.
Cross-dso cfi tests are disabled for now.

in lit tests
The Clang driver on macOS decides the deployment target based on various things, like your host OS version, the SDK version and some environment variables, which makes lit tests pass or fail based on your environment. Let's make sure we run all lit tests with `-mmacosx-version-min=${SANITIZER_MIN_OSX_VERSION}` (10.9 unless overriden).

Summary:
This patch is a refactoring of the way cmake 'targets' are grouped.
It won't affect non-UI cmake-generators.
Clang/LLVM are using a structured way to group targets which ease
navigation through Visual Studio UI. The Compiler-RT projects
differ from the way Clang/LLVM are grouping targets.
This patch doesn't contain behavior changes.

It's fixing compilation errors. The runtime is not yet working.
Missing features:
OverrideFunction for x64
an equiv function for inline asm (atomic_compare_exchange_strong)
shadow memory offset needs to be adjusted
RoundUpToInstrBoundary for x64
They will be implemented by subsequent patches.

Summary:
Rather than having to add new "experimental" options each time someone wants to work on bringing a sanitizer to a new platform, this patch makes options for all of them.
The default values for the options are set by the platform checks that would have enabled them, but they can be overridden on or off.

Without the --target flag, clang uses the mips64 triple which selects the n64 abi. We need to add --target=mips-linux-gnu, so that clang can select the correct abi for mips32r2.

cannot.

You can expect the sanitizers to be built under any of the following conditions:
1) CMAKE_C_COMPILER is GCC built to cross-compile to ARM
2) CMAKE_C_COMPILER is Clang built to cross-compile to ARM (ARM is default target)
3) CMAKE_C_COMPILER is Clang and CMAKE_C_FLAGS contains -target and --sysroot
