This change was partially scripted and partially done manually with vim
regex + manually placing the deleted constructors.
The script change looked for destructors in the public: section of a
class, if that existed the deleted constructors would go before the
destructor.
For manual placement I looked for any constructor in the public: section
of the corresponding class. If there wasn't one, then it would ideally
have gone as the first entry except below enums, classes and typedefs.
This may not have been perfect, but is hopefully good enough. Fingers
crossed.
#include "base/macros.h" is removed from files that don't use
ignore_result, which is the only other thing defined in base/macros.h.

As Mark noted in [1] ProcessMemory should accept VMSize instead of
size_t, the two types can differ on platforms where a cross-bitness
handler could cause a 32-bit handler to inspect a 64-bit process. By
centralizing the checks in ProcessMemory, we can leave the individual
platform-specific implementations (in ProcessMemory*::ReadUpTo) to
accept size_ts.

The ProcessMemoryTests didn't work on macOS because MultiprocessExec

There’s no reason for ProcessReader to own its ProcessMemoryLinux via

This was discovered in a trunk Clang build, during which a

The warning is not produced by earlier Clang versions or by GCC because
the “delete” happens in a system header, <memory>, when performed by
std::unique_ptr<>. Although ownership via std::unique_ptr<> is no longer
used, ProcessMemoryLinux is marked “final” because it ought to be.
