Teresa Johnson d495533497 Add interface to compute number of physical cores on host system ... Summary: For now I have only added support for x86_64 Linux, but other systems can be added incrementally. This is to be used for setting the default parallelism for ThinLTO backends (instead of thread::hardware_concurrency which includes hyperthreading and is too aggressive). I'll send this as a follow-on patch, and it will fall back to hardware_concurrency when the new getHostNumPhysicalCores returns -1 (when not supported for a given host system). I also added an interface to MemoryBuffer to force reading a file as a stream - this is required for /proc/cpuinfo which is a special file that looks like a normal file but appears to have 0 size. The existing readers of this file in Host.cpp are reading the first 1024 or so bytes from it, because the necessary info is near the top. But for the new functionality we need to be able to read the entire file. I can go back and change the other readers to use the new getFileAsStream as a follow-on patch since it seems much more robust. Added a unittest.
