The definitions in sanitizer_common may conflict with definitions from system headers because:
The runtime includes the system headers after the project headers (as per LLVM coding guidelines).
lib/sanitizer_common/sanitizer_internal_defs.h pollutes the namespace of everything defined after it, which is all/most of the sanitizer .h and .cc files and the included system headers with: using namespace __sanitizer; // NOLINT
This patch solves the problem by introducing the namespace only within the sanitizer namespaces as proposed by Dmitry.

This patch enables the safestack for aarch64. The frontend already have
it enabled on all supported architectures and no adjustment is required
in llvm.
The compiler-rt adjustments are basically add on the cmake configuration
to enable the tests and fix the pagesize debug check by getting its
value at runtime (since aarch64 has multiple pagesize depending of
kernel configuration).

- 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).

This patch clarifies the TODO note at the top of safestack.cc and brings
it more in sync with what we (the CPI team) actually plan to work on in
the future.

This patch adds runtime support for the Safe Stack protection to compiler-rt
(see http://reviews.llvm.org/D6094 for the detailed description of the
Safe Stack).
This patch is our implementation of the safe stack on top of compiler-rt. The
patch adds basic runtime support for the safe stack to compiler-rt that
manages unsafe stack allocation/deallocation for each thread.
Original patch by Volodymyr Kuznetsov and others at the Dependable Systems
Lab at EPFL; updates and upstreaming by myself.
