bmeurer@chromium.org	caca2b32cf	Replace OS::NumberOfCores() with CPU::NumberOfProcessorsOnline(). The name NumberOfCores is misleading, as it does not return the actual number of cores. While NumberOfProcessorsOnline is also not a great name, it's at least consistent with the operating system terminology.

bmeurer@chromium.org	5768fcf12c	Fix the CPU feature detection. Move all of the CPU detection logic to the CPU class, and make all other code use the CPU class for feature detection. This also fixes the ARM CPU feature detection logic, which was based on fragile string search in /proc/cpuinfo. Now we use ELF hwcaps if available, falling back to sane(!!) parsing of /proc/cpuinfo for CPU features. The ia32 and x64 code was also cleaned up to make it usable outside the assembler.

Replace OS::NumberOfCores() with CPU::NumberOfProcessorsOnline().

The name NumberOfCores is misleading, as it does not return the
actual number of cores. While NumberOfProcessorsOnline is also
not a great name, it's at least consistent with the operating
system terminology.
