ppc: Create disassemble.h to extract instruction fields
This is used in a couple places in KVM, but isn't KVM-specific.
However, this patch doesn't modify other in-kernel emulation code:
- xmon uses a direct copy of ppc_opc.c from binutils
- emulate_instruction() doesn't need it because it can use a series
of mask tests.
