Added a new CC flag into build32 and build64 Makefiles to distinguish
whether compiling to 32-bit or 64-bit code.
[Lionel Debroux: rebased on the memrw functions refactor.]

* Add a file containing useful macro definitions, currently a single top-level macro for obtaining the size of an array; use it to replace a sizeof(x) / sizeof(x[0]) construct in system/smbus.c . This requires switching the GCC build mode from C11 to C11 with GCC extensions.
* Initial NUMA awareness (#12) support: parse the ACPI SRAT to build up new internal structures related to proximity domains and affinity; use these structures in setup_vm_map() and calculate_chunk() to skip the work on the processors which don't belong to the proximity domain currently being tested.
Tested on a number of 1S single-domain, 2S multi-domain and 4S multi-domain platforms.
SKIP_RANGE(iterations) trick by Martin Whitaker.
* For 64-bit images, use the physical address as the test pattern in test 2.
This will make it easier to diagnose faults.
* Disable test 1 by default (issue #155).
Test 2 provides the same test coverage. Test 1 may make it slightly easier
to diagnose faults with a 32-bit image, so leave it as an option.
* For 32 bit images, use the physical address to generate the offset in test 2.
Detecting a stage change and using that to reset the offset counter
could fail when the config menu was used to skip to the next test
(issue #224).
Mostly we write and read large chunks of data which will make it likely
that the data is no longer in the cache when we come to verify it. But
this is not always true, and in any case, we shouldn't rely on it.
