DEVICE_EXTENSION VK_KHR_shader_terminate_invocation

# A test for a coverage-gap found by the GraphicsFuzz project.

|
# Short description: A fragment shader that covers specific LLVM code paths
|
|
|
|
# The test passes because the shader always writes red.
|
|
|
|
# Optimized using spirv-opt with the following arguments:
|
|
# '-O'
