ba19e48d90 Fix C++ compiler option checks, increase max stack frame size
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).

6a6c931317 Move away from multiple inheritance
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.

c2b7cffe78 Minielf: Use a template to load integers
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.
