cpu: add CPU features for s390x

Add basic support for IBM Z (s390x) CPU feature (known as
'facilities') detection.

Note that some of these features are mandatory when using the Go
compiler (for example, ldisp and eimm) but aren't mandatory when
using gccgo.

Cryptographic function detection is not yet implemented for
gccgo.
