This adds support for 64-bit instructions to decodetree.py.
It will be necessary to later on use decodetree to implement
the new 64-bit Power ISA 3.1 instructions.
While doing this change, I thought it would also be nice to be
able to specify different sizes for each field in arg structs and
also infer whether to use signed/unsigned data types based on
the field definition. But those would be different changes,
anyway, and I limited myself to using int64_t for the data type
of fields in arg structs when insnwidth == 64.
