This patch implements two changes:
- Move processor feature definition into a new file SystemZFeatures.td,
and provide explicit lists of supported and unsupported features for
each level of the z/Architecture. This allows specifying unsupported
features in the scheduler definition files for each processor.
- Add optional aliases for the -mcpu processor names according to the
level of the z/Architecture, for compatibility with other compilers
on the platform. The supported aliases are:
-mcpu=arch8 equals -mcpu=z10
-mcpu=arch9 equals -mcpu=z196
-mcpu=arch10 equals -mcpu=zEC12
-mcpu=arch11 equals -mcpu=z13
