1b7d5d849f 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.

85248a4b18 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.

ee09a39aef 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.
