IR: add support for `discard` statement (#261)
- Add definition of `discard` instruction
- A `discard` is a terminator instruction, just like `returnVoid`
- Lower `DiscardStmt` in AST to a `discard` instruction in the IR
- Emit `discard` instruction as a `discard;` statement when emitting HLSL/GLSL
- Add a test case using the "graphics compute" mode that tests discard. The test writes to one entry in a UAV before doing a conditional (always true at runtime) discard, and then writes to another entry; we expect to see the results of the first write, but not the second.
