enable most of IA-32 specific code to be used in amd64 (resides in directory lib/sysdep/x86_x64) bits: add IsBitSet remove mem_PageSize (use os_cpu_PageSize instead) cpuid: change interface to allow gracefully supporting later subfunctions that require input parameters amd64_asm.asm: add amd64 implementation of cpuid cpu: move functions provided by OS to sysdep/os_cpu.cpp cpu topology: avoid trouble when process affinity is set by remapping processor numbers to 0..PopulationCount(processAffinity) topology.cpp: move ex-ia32 topology code here. This was SVN commit r5945.
