CMake build rules listed -I flags for two different libc++ header
locations which broke when libc++ headers started using include_next.
Also change -I to -isystem to avoid compiler warning about
include_next.

This is an implementation of
https://github.com/google/sanitizers/issues/579
It has a number of advantages over the current mapping:
* Works for non-PIE executables.
* Does not require ASLR; as a consequence, debugging MSan programs in
gdb no longer requires "set disable-randomization off".
* Supports linux kernels >=4.1.2.
* The code is marginally faster and smaller.
This is an ABI break. We never really promised ABI stability, but
this patch includes a courtesy escape hatch: a compile-time macro
that reverts back to the old mapping layout.

Summary:
Since r223145 we don't include sanitizer_allocator_internal.h into
sanitizer_symbolizer.h, so we can have undefined reference to
Internal{Alloc, Free} stuff into sanitizer_symbolizer_libbacktrace.cc under
SANITIZER_CP_DEMANGLE macro.
This patch simply includes appropriate header into
sanitizer_symbolizer_libbacktrace.h to resolve the issue.

cl does not support the same intrinsics as clang. Provide implementations for
the intrinsics using MSVC builtins.

Unfortunately, int_utils.h needs to depend on int_lib for the common macro
definitions. However, currently, int_utils.h is included by int_lib.h. Reorder
the inclusion to work around this.

Summary: This is the Makefile analog of r247833, except that the test also had to be changed such that clang actually attempts to link the program as opposed to just building it. Because of that change, I also switched the order to checking for ld/clang architecture support, because now lack of ld support would make the clang check fail. This fixes PR24776.

This patch add support for leak sanitizer for aarch64. Similar to
MIPS it uses a SizeClassAllocator32 due VMA constraints (aarch64
currently supports 39 and 42-bit VMA).

- Trim spaces.
- Use nullptr in place of 0 for pointer variables.
- Use '!p' in place of 'p == 0' for null pointer checks.
- Add blank lines to separate function definitions.
- Add 'extern "C"' or 'namespace foo' comments after the appropriate
closing brackets
This is a continuation of work from 409b7b82. The focus here is on the
various sanitizers (not sanitizer_common, as before).

We need to make sure that if you change the builtin filter lists CMake re-generates its configurations so it includes the right builtins in the generated libraries.

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