Etienne Bergeron ab42f4ddba [compiler-rt] Fix VisualStudio virtual folders layout
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.

Peter Collingbourne 5788e1259b Introduce stats and stats_client libraries.
This is part of a new statistics gathering feature for the sanitizers.

Evgeniy Stepanov cfe331042a Fix CMake warning in CFI tests.
CFI tests do not require the CFI runtime library on Windows.
Do not add "cfi" as a dependency of "check-cfi" in that case.

Evgeniy Stepanov da1cf9287c Cross-DSO control flow integrity (compiler-rt part).
This is an initial version of the runtime cross-DSO CFI support
library.

It contains a number of FIXMEs, ex. it does not support the
diagnostic mode nor dlopen/dlclose, but it works and can be tested.
Diagnostic mode, in particular, would require some refactoring (we'd
like to gather all CFI hooks in the UBSan library into one function
so that we could easier pass the diagnostic information down to
__cfi_check). It will be implemented later.

Once the diagnostic mode is in, I plan to create a second test
configuration to run all existing tests in both modes. For now, this
patch includes only a few new cross-DSO tests.

Chris Bieneman 5c64ddfa88 Revert "[CMake] Provide options for toggling on and off various runtime libraries."
This reverts r255170. This change caused a bunch of bot failures and needs to be revised.

Chris Bieneman e82ad46f15 [CMake] Provide options for toggling on and off various runtime libraries.
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.

Reid Kleckner 45ebaf1840 [cmake] Hoist check for LLD sources up into root CMakeLists.txt
We will use this for ASan on Windows soon. When the ELF port of LLD
matures, we can add other sanitizer integration tests to make sure they
work with LLD.

Peter Collingbourne 702548d9ea CFI: Get check-cfi passing on Windows.
Specifically:

- Start using %expect_crash.

- Provide an implementation of __ubsan::getDynamicTypeInfoFromVtable
  for the Microsoft C++ ABI. This is all that is needed for CFI
  diagnostics; UBSan's -fsanitize=vptr also requires an implementation of
  __ubsan::checkDynamicType.

- Build the sanitizer runtimes against the release version of the C
  runtime, even in debug builds.

- Accommodate demangling differences in tests.

Peter Collingbourne 4be9b40091 CFI: Add a check-cfi-and-supported rule.
This rule works like check-cfi, but fails if the tests are unsupported.
This is useful to run on bots if we want to be sure that the tests aren't
silently being skipped.
