Build fixes for LLVM 3 backend

Ctlz and Cttz are stubbed for now. Will fix after the builds turn green. Bug: b/130343040 Tests: dEQP-VK.glsl.builtin.precision.* Tests: dEQP-VK.glsl.builtin.function.integer.findMSB.* Change-Id: Ibff6a52bee7f5440c536dfc7a61ad4ba3e96743d Reviewed-on: https://swiftshader-review.googlesource.com/c/SwiftShader/+/28868Tested-by: 's avatarBen Clayton <bclayton@google.com> Kokoro-Presubmit: kokoro <noreply+kokoro@google.com> Reviewed-by: 's avatarNicolas Capens <nicolascapens@google.com>
