b0b6a8f693 Define register banks.
Add a RegBank class for describing CPU register banks.

Define register banks for all the ISA stubs. The ARM32 floating point
bank in particular requires attention.

77c672a279 Add stubs for Intel and ARM architectures.
The Intel ISA handles both 32-bit and 64-bit code.

ARM is split into separate arm32 and arm64 ISAs since the architectures
have little in common in instruction encodings and register files.

6748817985 Add PEP 484 type annotations to a bunch of Python code.
Along with the mypy tool, this helps find bugs in the Python code
handling the instruction definition data structures.

e7f30a40b4 Move the 'meta' dir to 'lib/cretonne/meta'.
The 'lib/cretonne' directory will be the new root of a stand-alone
cretonne crate containg both Python and Rust sources.

This is in preparation for publishing crates on crates.io.
