fixes+improvements from work: - add AlignedAllocator - an STL allocator that returns cache-line-aligned objects (required to avoid RFOs when threads write to various independent items in a container) - bits: bit_mask can now be used for N=0..numBits (works around full-word-shifts-are-undefined issue) - precompiled.h: remove scoped_ptr, add function-related stuff from TR1 - numa: . add numa_IsMemoryInterleaved . numa_Allocate is now able to allocate large pages as well (reduces TLB misses) - os_cpu: interface change to support 32-bit apps running on WoW64 systems with > 4 GB of memory - topology: use new x86_x64_EnumerateCaches API; fix detection of cache ID - x86_x64: provide the means of enumerating all caches returned by CPUID and detect L1 cache size This was SVN commit r6004. 2008-06-01 10:25:12 +02:00			`LIB_API size_t rand(size_t min_inclusive, size_t max_exclusive);`
