```
spirv: update spec generator

For module parsing and assembling, we will also need to know
all of the SPIR-V extensions and their instructions. This commit
updates the generator to generate those. Because there are
multiple instruction sets that each have a separate list of Opcodes,
no separate enum is generated for these opcodes. Additionally, the
previous mechanism for runtime instruction information, `Opcode`'s
`fn operands()`, has been removed in favor for
`InstructionSet.core.instructions()`.

Any mapping from operand to instruction is to be done at runtime.
Using a runtime populated hashmap should also be more efficient
than the previous mechanism using `stringToEnum`.

```
