Is there a macro that says that exceptions are off? We can key off of that and
#define CRASHPAD_NOEXCEPT empty in util/stdlib/aligned_allocator.h.

We could do that, but it seems more fragile.
My impression is that we want to tell the compiler that no exceptions will be
thrown so that it can generate better code. The warning seems to be more related
to nothrow semantics where the compiler was required to enforce the semantics.
