PnaclCoordinator: Use llc's module-splitting for pexe compilation

When there is more than 1 core in the system, request extra temp files
and use LLC's StreamInitWithSplit rpc to enable module splitting.
If the RPC fails, fall back to StreamInitWithOverrides.

Add a private Pepper interface to get the cpu count rather than
duplicating base::SysInfo in the plugin.
