With PR #107223 and PR #107403, ASan testing can be enabled on SPARC.
This patch does so, 32-bit only on both Solaris and Linux. There is no
64-bit support even in GCC.
Apart from the obvious CMake changes, this patch includes a couple of
testcase adjustments necessary for SPARC:
- In `asan_oob_test.cpp`, the `OOB_int` subtest needs to be disabled: it
performs unaligned accesses that cannot work on a strict-alignment
target like SPARC.
- `asan_test.cpp` needs to disable subtests that depend on support for
`__builtin_setjmp` and `__builtin_longjmp`.
- `zero_page_pc.cpp` reports `0x5` as the faulting address on access to
`0x4`. I don't really know why, but it's consistent between Solaris and
Linux.
Tested on `sparcv9-sun-solaris2.11` and `sparc64-unknown-linux-gnu`.
1. Move checks into parent test/CMakeLists.txt
2. COMPILER_RT_INCLUDE_TESTS disable both lit and
gtests. Before it was very inconsistent between
sanitizers.
Update the folder titles for targets in the monorepository that have not
seen taken care of for some time. These are the folders that targets are
organized in Visual Studio and XCode
(`set_property(TARGET <target> PROPERTY FOLDER "<title>")`)
when using the respective CMake's IDE generator.
* Ensure that every target is in a folder
* Use a folder hierarchy with each LLVM subproject as a top-level folder
* Use consistent folder names between subprojects
* When using target-creating functions from AddLLVM.cmake, automatically
deduce the folder. This reduces the number of
`set_property`/`set_target_property`, but are still necessary when
`add_custom_target`, `add_executable`, `add_library`, etc. are used. A
LLVM_SUBPROJECT_TITLE definition is used for that in each subproject's
root CMakeLists.txt.
When running tests like SanitizerCommon-asan-x86_64-Linux :: Linux/crypt_r.cpp,
it may attempt to use the host header crypt.h rather than a sysroot header.
This is significant in the event where struct crypt_data defined on host is
different from the sysroot used to make the sanitizer runtime libraries. This
can result in logical differences between the expected size/layout of struct
crypt_data known by sanitizers and the strict crypt_data provided by the host crypt.h.
Since tests should still use the CMAKE_SYSROOT, this ensures that CMAKE_SYSROOT
is propagated to compiler-rt tests.

As code diverge from Google style we need
to add more and more exceptions to suppress
conflicts with clang-format and clang-tidy.
As this point it does not provide a additional value.

The recent suffix-log-path_test.c checks for a full stacktrace and
since on some arm-linux-gnu configuration the slow unwinder is used
on default (when the compiler emits thumb code as default), it
requires -funwind-tables on tests.
It also seems to fix the issues disable by d025df3c1de.

During the initial Solaris sanitizer port, I missed to enable the
`sanitizer_common` and `ubsan_minimal` testsuites. This patch fixes this,
correcting a few unportabilities:
- `Posix/getpass.cpp` failed to link since Solaris lacks `libutil`.
Omitting the library lets the test `PASS`, but I thought adding `%libutil`
along the lines of `%librt` to be overkill.
- One subtest of `Posix/getpw_getgr.cpp` is disabled because Solaris
`getpwent_r` has a different signature than expected.
- `/dev/null` is a symlink on Solaris.
- XPG7 specifies that `uname` returns a non-negative value on success.
Tested on `amd64-pc-solaris2.11` and `sparcv9-sun-solaris2.11`.

When building on `sparc64-unknown-linux-gnu`, I found that a large number
of `SanitizerCommon-asan-sparc*-Linux` tests were `FAIL`ing, like
SanitizerCommon-asan-sparc-Linux :: Linux/aligned_alloc-alignment.cpp
[...]
SanitizerCommon-asan-sparcv9-Linux :: Linux/aligned_alloc-alignment.cpp
[...]
many of them due to
fatal error: error in backend: Function "_Z14User_OnSIGSEGViP9siginfo_tPv": over-aligned dynamic alloca not supported.
which breaks ASan on Sparc. Currently ASan is only built for the benefit
of `gcc` where it does work. However, when enabling the compilation in
`compiler-rt` to make certain it continues to build, I missed
`compiler-rt/test/sanitizer_common` when disabling ASan testing on Sparc
(it's not yet enabled on Solaris).
This patch fixes the issue.
Tested on `sparcv9-sun-solaris2.11` with the `sanitizer_comon` testsuite enabled.

These lit configuration files are really Python source code. Using the
.py file extension helps editors and tools use the correct language
mode. LLVM and Clang already use this convention for lit configuration,
this change simply applies it to all of compiler-rt.

Summary:
This replaces the sanitizer tool list (used for generating
sanitizer_common configurations) with a tool list derived from
existing build system information.
Previously sanitizer_common had its own list of supported sanitizer
tools. This was bad because it was out of sync with the rest of the
build system. Notably it meant that the sanitizer_common runtime was
only being tested on Darwin the ASan dylib and not the other sanitizer
dylibs that are built for Darwin (LSan, TSan, and UBSan).
Unfortunately enabling the tests against other sanitizer dylibs has lead
to some test failures on Darwin. For now they've been marked as
XFAIL until the failures can investigated properly.
For Windows and Android we use the old sanitizer tool list to try avoid
bot breakages.

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?

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).

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.

There are a number of issues with unit tests on Darwin. These patches address the following:
* Unit tests should be passed -arch (-m32/-m64 isn't sufficient)
* Unit tests should be passed ${DARWIN_osx_CFLAGS} because they're being built for OS X
* Test architectures should be filtered based on base system capabilities (i.e. don't try running x86_64h tests on pre-haswell hardware).
