24e0828d20 Generate a constant hash table for recognizing opcodes. 
Use a simple quadratically probed, open addressed hash table. We could use a
parfect hash function, but it would take longer to compute in Python, and this
is not in the critical path performancewise.

3dcd2f8e58 Generate an opcode_name() function. 
This function returning a &'static str is more primitive that the Display
implementation. It allows the opcode strings to be reused by the parser.

d650d551a0 Include generated Opcode enum in the immediates module. 
Generate nice doc comments for the Opcode enum variants that 'cargo doc'
will pick up.

Include a `Display` trait implementation that prints the lower
snake-case version of the opcode name.

15f39c776c Begin source generation. 
Start out easy by emiting an opcodes.rs file containing an opcode enumeration.
