2018-12-4 update
New feature and improvement
* Enable VK_EXT_scalar_block_layout extension
* Enable VK_KHR_swapchain_mutable_format extension
* Enable on-chip GSVS ring on GFX9, seeing up to 10% performance gain
* Add dccBitsPerPixelThreshold setting
* Re-enable tracing of missing registers in thread trace
* Remove some useless settings
Issue fix
* Undefined reference to vk::OverrideDispatchTable_ND(vk::DispatchTable*)
* Errors with multiple monitors and direct display
* dEQP-VK.api.device_init.create_instance_device_intentional_alloc_fail test failure
* Crash issue on Raven caused by the implementation of VK_AMD_memory_overallocation_behavior extension
* dEQP-VK.glsl.atomic_operations.*_*signed64bit_* failure on gfx7
* ELEX crash with Steam Proton
* CopyTextureRegion failure when copying a MSAA Resource in D32_FLOAT or D16_UNORM to a R32_UINT format
* GFX9: CB_DCC_CONTROL register is programmed incorrectly
* Perf counter instance incorrect calculation
1. Clean the submodule
2. Unused variable is treated as error on Ubuntu 16.04 gcc-5.4, turn it off
3. Add "Driver installation instruction" into the release notes
2018-11-19 update
* Enable sparse support by default
* Enable VK_AMD_memory_overallocation_behavior extension
* Enable degenerate triangles for conservative rasterizations
* Add setting for exiting after compilation failure
* Add setting CsCuEnLimitMask for limiting CUs enabled for compute shaders
* Add the ability to dump debug stack traces
* Set default -log-file-dbgs to "" (meaning stderr): this brings amdllpc into line with other LLVM tools
* Can't clear a mutable format image
* CTS memory.pipeline_barrier.transfer_dst_storage_image tests fail
* MGPU asserts when creating graphics pipeline
* Wrong target device ID passed to PAL
* Dual source bend is being enabled when blending is disabled
* Regression dEQP-VK.wsi.wayland.swapchain.create.min_image_count test crashes
* Dependency on x11/xcb libraries even there is no x11/xcb surface created
* Assert in dEQP-VK.binding_model.descriptorset_random.*
