  Add PISA register file, instruction set, and MC layer

Add the PISA register file and register-bank descriptions, the instruction
formats and definitions, and the MC/assembly layer (instruction printer,
register and code encoders, target streamer, MC target description and the
supporting enums), replacing the stub descriptions from
the initial target skeleton.

This provides the instruction-set description and assembly-emission
foundation. The GlobalISel lowering and instruction selection that consume it
are added in the following changes.
