Fix the Darwin logic so that -msse3 is only used on macOS, and
-fomit-frame-pointer is not used on armv7/armv7k/armv7s.

The buildbots have shown that -Wstrict-prototypes behaves differently in GCC
and Clang so we should keep it disabled until Clang follows GCC's behaviour

Clang 5 supports -Wstrict-prototypes. We should use it to catch any C

Summary:
Before this change we seemed to not be running the unit tests, and therefore we
set out to run them. In the process of making this happen we found a divergence
between the implementation and the tests.
This includes changes to both the CMake files as well as the implementation and
headers of the XRay runtime. We've also updated documentation on the changed
functions.

Summary:
This code already works and passes some number of tests.
There is need to finish remaining sanitizers to get better coverage.
Many tests fail due to overly long file names of executables (>31).
This is a current shortcoming of the NetBSD 8(beta) kernel, as
certain functions can fail (like retrieving file name of executable).

Summary:
An implementation of ubsan runtime library suitable for use in production.
Minimal attack surface.
* No stack traces.
* Definitely no C++ demangling.
* No UBSAN_OPTIONS=log_file=/path (very suid-unfriendly). And no UBSAN_OPTIONS in general.
* as simple as possible
Minimal CPU and RAM overhead.
* Source locations unnecessary in the presence of (split) debug info.
* Values and types (as in A+B overflows T) can be reconstructed from register/stack dumps, once you know what type of error you are looking at.
* above two items save 3% binary size.
When UBSan is used with -ftrap-function=abort, sometimes it is hard to reason about failures. This library replaces abort with a slightly more informative message without much extra overhead. Since ubsan interface in not stable, this code must reside in compiler-rt.

function.
Summary:
This change hides all the initialization of thread_local variables used
by the XRay FDR mode implementation behind a function call. This makes
initialization of thread-local data to be done lazily, instead of
eagerly when they're done as globals. It also gives us an isolation
mechanism if/when we want to change the TLS implementation from using
the C++ thread_local keyword, for something more ad-hoc (potentialy
using pthread directly) on some platforms or set-ups where we cannot use
the C++ thread_local variables.

Summary:
The NetBSD's 8(beta) versions of kernel functions to retrieve
program name (vnode to path translator) and process memory
map have internal limit of processing filenames with maximum
of 31 characters.
Filenames like Asan-x86_64-with-calls-Noinst-Test break this
limit and affect tests. Rename "-with-calls" to "-calls".
This changes fixes all issues for the Address Sanitizer test
target (check-asan) on the current NetBSD support caused
by long filenames.

Remove the explicit i686 target that is completely duplicate to
the i386 target, with the latter being used more commonly.
1. The runtime built for i686 will be identical to the one built for
i386.
2. Supporting both -i386 and -i686 suffixes causes unnecessary confusion
on the clang end which has to expect either of them.
3. The checks are based on wrong assumption that __i686__ is defined for
all newer x86 CPUs. In fact, it is only declared when -march=i686 is
explicitly used. It is not available when a more specific (or newer)
-march is used.
Curious enough, if CFLAGS contain -march=i686, the runtime will be built
both for i386 and i686. For any other value, only i386 variant will be
built.

Summary:
Currently `TransferBatch` are located within the same memory regions as
"regular" chunks. This is not ideal for security: they make for an interesting
target to overwrite, and are not protected by the frontend (namely, Scudo).
To solve this, we re-introduce `kUseSeparateSizeClassForBatch` for the 32-bit
Primary allowing for `TransferBatch` to end up in their own memory region.
Currently only Scudo would use this new feature, the default behavior remains
unchanged. The separate `kBatchClassID` was used for a brief period of time
previously but removed when the 64-bit ended up using the "free array".

of the sled
Summary:
XRay has erroneously been returning the address of the first sled in the
instrumentation map for a function id instead of the (runtime-relocated)
functison address. This causes confusion and issues for applications
where:
- The first sled in the function may not be an entry sled (due to
re-ordering or some other reason).
- The caller attempts to find a symbol associated with the pointer at
runtime, because the sled may not be exactly where the function's
known address is (in case of inlined functions or those that have an
external definition for symbols).
This fixes http://llvm.org/PR34340.

Heretofore asan_handle_no_return was used only by interceptors,
i.e. code private to the ASan runtime. However, on systems without
interceptors, code like libc++abi is built with -fsanitize=address
itself and should call asan_handle_no_return directly from
__cxa_throw so that no interceptor is required.
