IR: support for select and negate (#257)
- During IR emit, treat a "select" expression (`?:` operator) like any other `InvokeExpr`, since it will have an `__intrinsic_op` modifier attached to turn it into a `select` instruction.
- During HLSL/GLSL emit from IR, turn a `select` instruction into a `?:` expression
- Also add support for the `neg` instruction during HLSL/GLSL emit
Note that right now we are assuming HLSL semantics for `?:` where it does not short-circuit. Correctly handling the GLSL case would require going back to special-case codegen for `SelectExpr`, but we can cross that bridge when we come to it.
