* Fix missing clobber in blas_quickdivide assembly

make it so that

if (foo)
	RMB;
else
	MB;

is always done correctly and without syntax surprises

Whie on x86(64) one does not normally need full memory barriers, it's
good practice to at least use compiler barriers for places where on other
architectures memory barriers are used; this prevents the compiler
from over-optimizing.

Avoid out-of-bounds accesses in blas_quickdivide on big X86 systems

Should fix #1541

With this change, OpenBLAS builds and all tests pass on OpenBSD 6.2
using Clang. Tested on x86-64 only, with and without DYNAMIC_ARCH=1.

Putting the procedure there is an MSVC-ism, where it is optional. GCC silently ignores and Clang errors, so it is best to remove this.

Conflicts:
	driver/others/memory.c

to be used on armv5 and new platforms

- use on arm, arm64 and any new platform
- use faster integer math instead of double
- use similar scale as rdtsc so that timeouts work

Disable CBLAS and LAPACK.
