Summary:
These tests were not being run because the yaml extension
wasn't be picked up by lit.
This change also fixes the tests which themselves were broken.

This was originally there for the _POSIX_THREADS define, to detect the
presence of pthreads. That went away with the externalized threading
support, so the include can go away too.
config.h is now completely empty. A follow-up commit will remove it
entirely.

TSan reports a false positive when using xpc_connection_cancel. We're missing a happens-before edge from xpc_connection_cancel to the event handler on the same connection.

an ObjC object pointer
When ARC is enabled in Objective-C++, comparisons between a pointer and
Objective-C object pointer typically result in errors like this:
"invalid operands to a binary expression". This error message can be quite
confusing as it doesn't provide a solution to the problem, unlike the non-C++
diagnostic: "implicit conversion of Objective-C pointer type 'id' to C pointer
type 'void *' requires a bridged cast" (it also provides fix-its). This commit
forces comparisons between pointers and Objective-C object pointers in ARC to
use the Objective-C semantic rules to ensure that a better diagnostic is
reported.

I am working on improving our internal bot infrastructure. One thing
that is unique to the ps4 is that we want to run the posix tests, but
have to execute them on windows.
We currently have a local hack to use a shell on windows, but it is
pretty much impossible to get all all the tools to play nice with all
the heuristics for what is a path and what is a command line option.
This adds support LIT_USE_INTERNAL_SHELL and I will then try to fix
the tests that fail with it but adding the missing features.

This reverts r299062, which caused build failures on Windows.
It also reverts the attempts to fix the windows builds in r299064 and r299065.
The introduction of namespace llvm::sys::detail makes MSVC, and seemingly also
mingw, complain about ambiguity with the existing namespace llvm::detail.
E.g.:
C:\b\slave\sanitizer-windows\llvm\include\llvm/Support/MathExtras.h(184): error C2872: 'detail': ambiguous symbol
C:\b\slave\sanitizer-windows\llvm\include\llvm/Support/PointerLikeTypeTraits.h(31): note: could be 'llvm::detail'
C:\b\slave\sanitizer-windows\llvm\include\llvm/Support/Host.h(80): note: or 'llvm::sys::detail'
In r299064 and r299065 I tried to fix these ambiguities, based on the errors
reported in the log files. It seems however that the build stops early when
this kind of error is encountered, and many build-then-fix-iterations on
Windows may be needed to fix this. Therefore reverting r299062 for now to
get the build working again on Windows.

This refactors getHostCPUName so that for the architectures that get the
host cpu info on linux from /proc/cpuinfo, the /proc/cpuinfo parsing
logic is present in the build, even if it wasn't built on a linux system
for that architecture.
Since the code is present in the build, we can then test that code also
on other systems, i.e. we don't need to have buildbots setup for all
architectures on linux to be able to test this. Instead, developers will
test this as part of the regression test run.
As an example, a few unit tests are added to test getHostCPUName for ARM
running linux. A unit test is preferred over a lit-based test, since the
expectation is that in the future, the functionality here will grow over
what can be tested with "llc -mcpu=native".
This is a preparation step to enable implementing the range of
improvements discussed on PR30516, such as adding AArch64 support,
support for big.LITTLE systems, reducing code duplication.

Turns out integerPartWidth only explicitly defines the width of the tc functions in the APInt class. Functions that aren't used by APInt implementation itself. Many places in the code base already assume APInt is made up of 64-bit pieces. Explicitly assuming 64-bit here doesn't make that situation much worse. A full audit would need to be done if it ever changes.

Both libc++ and libc++abi export a weak definition of operator
new/delete. On Darwin, this can often cause dirty __DATA in the
shared cache when having to switch from one to the other. Instead,
libc++ should reexport libc++abi's implementation of these symbols.

Until llvm-xray starts running/supporting binaries that are not ELF64 we
only run the FDR tests on x86_64-linux. Previous changes caused the
tests to not actually run on x86_64.

When -fsanitize-address-use-after-scope is used, the instrumentation produces line numbers in stack frame descriptions. This patch make sure the ASan runtime supports this format (ParseFrameDescription needs to be able to parse "varname:line") and prepares lit tests to allow line numbers in ASan report output.

implementation that uses the llvm-xray tooling to verify that what we
are both writing and reading the data in a consistent manner.
