zra@google.com 6f2096face Refactors some CPU feature detection into new class CpuInfo, and uses new information in VM service. 
This change rewrites the code from the ARM assembler for parsing /proc/cpuinfo on Linux and Android, and collects it into a CpuInfo class that can be used for other architectures as well. This code is in cpuinfo_*.cc. /proc/cpuinfo equivalents are used for Mac and Windows. CpuInfo is used by the VM service to report on the hardware dart is running on. In the future CpuInfo can also be used here to provide more information.
