Log:	Raise ProcessorAutodetectError for unknown machine names

	Previously this function was only used for the JIT, so it only had
	to support machines that the JIT supports. Now, it's used by
	rpython.rlib.rawstorage, and should raise an appropriate exception,
	rather than KeyError, on unknown machines.
