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.

v2:
- Added information about the field data types used in arg structs
