Newer versions of libunwind use `PTRACE_GETREGSET` to obtain register data.
This change should make it easier to upgrade the libunwind dependency.

The former fixes the actual compiler option checks in `CMakeLists.txt`.
The latter is to avoid a compiler warning in `sandboxed_api/sandbox2/util.cc`,
which needs a stack frame size bigger than pthread's default value (16K).

Raw `SAPI_RAW_PCHECK` may dump core, depending on environment settings
(issue #89).
This is undesirable in the face of invalid command-line arguments.

The newer version includes a fix for a compilation error on newer
systems (specfically, `benchmark_register.h` was missing an include
for the `limits` header).

__sanitizer_sandbox_on_notify is not tsan specific.
It's empty for other sanitizers now, but we are going to need it soon.

This change is a first step to make the SAPI variable hierarchy more sensible.
It turns the `Reg<T>` class into a descendant of `Pointable`, but without
making its `PtrXXX()` methods public (hence the `using` statements). Further
changes are needed to restructure this.
There are no functional changes and the class sizes, including vtables, should
not change.

Different versions of the `elf.h` header define their own integer types. For
example, even on LP64 systems, a 64-bit ELF integer types may decay into
`unsigned long long` instead of `unsigned long`.
This change replaces the various overloads with a single function template
that is well-defined for all integral types.
