This should resolve PR23162. This patch has two parts.
First we need to check the error code from xcodebuild when querying for SDKs, second if the OS X SDK is not discovered, we ensure that /usr/include exists and use / as the OS X sysroot.

Summary:
One of the big limitations we have in the compiler-rt build system today is that we cannot bootstrap building the builtins because you need a fully functional toolchain to pass CMake's tests.
This change adds support for compile only tests.
It is NFC because nothing is using the compile-only tests yet.
I believe this is the last separable part of D16653.

This change modifies find_darwin_sdk_dir to set a variable if a Darwin "Internal" SDK is present which allows CMake to disable components that require internal-only APIs.
This mechanism is then used to disable TSan when an internal SDK is not present.

llvmBufferWriter and a few related symbols were missing from libclang_rt
on Darwin (PR26002). This should fix the problem.

For OS X builds of compiler-rt, we run `darwin_test_archs` to determine which architectures can the toolchain target. This detection takes quite a long time, and the result is always the same (as long as you don't upgrade your OS, system headers or toolchain). Let's cache the result.

Turns out that there are some checks in the backend that change code generation for armv7 if you are building against an iOS sys root. For the macho_embedded builtins we really don't want that.
llvm-svn: 253064
We need to add -fPIC to the flags for the builtins in case PIC was turned off at a higher level. We also want to set ENABLE_PIC to Off when building the macho_embedded builtins so the top-level settings don't impact that build.

Setting CMAKE_*_FLAGS isn't sufficient here because CMAKE_*_FLAGS_${CMAKE_BUILD_TYPE} can override the flags, and there is no way to safely clear that because it is a cached variable (<sarcasm> YAY! </sarcasm>).
llvm-svn: 252807
* Setting CMAKE_*_FLAGS_${BUILD_TYPE} isn't really needed since we're setting the same value everywhere
* functions sanitize variables differently from macros, darwin_add_embedded_builtin_libraries should be a macro otherwise it won't alter the variables.

This commit reverts r252525. I was not really thinking about this fix properly. This doesn't work because it relys on try_compile checks which do a full compile & link. I'm going to put in a temporary solution as an interm step until we have a way to perform compiler checks without linking.

Not making sure there are thin libraries results in some difficult to diagnose build failures. This check should make those build failures go away.

Summary: This ports functionality from the clang_macho_embedded.mk platform makefile over to CMake.

We don't want to filter out the builtins that are present in libSystem like we do for the normal builtins because kexts can't link libSystem, but we should filter out all the builtins that are generally not supported on the OS and architecture.
llvm-svn: 248756
For Darwin simulator platforms we shouldn't build the cc_kext builtins at all because they aren't applicable, and we should includ the simulator builtins as slices inside the main platform builtin library.

Rename darwin_read_exclude_file to more generic darwin_read_list_from_file, and make it take the file path instead of constructing it so it can be reused more freely.

OS and ARCH must be specified, but minimum version may not. Excluding the minimum version will only apply the filters for builtins not supported by the OS and OS-Arch pair.
