Summary:	Empty switch statements generated by opcode_generator.rb

Description Ian Grunert 2023-07-23 13:27:58 PDT

AirOpcodeGenerated.h generates warnings when built with MSVC due to switch statements with no case clause (only default). This builds without warnings in clang but generates an extraneous jmp instruction to the next line.

Fix opcode_generator.rb to stop generating these empty switch statements.
