As reported in #1624, Ubuntu 14.04 LTS still uses CMake 2.8.12 which
does not support the Threads::Threads target (added in CMake 3.1).
This could be reverted once the required CMake version is bumped to 3.1+.
Would typically be pthreads.
Without this, '-Wl,--no-undefined' would output these errors:

* Changed unit tests to only record known the validation pass/fail
status
* errors are output as part of the failure message if the result is
unexpected
* can turn off validation for each test individually
* Moved some SPV_KHR_vulkan_memory_model tests to be compiled for Vulkan
1.1
Without this commit, if the XfbStride was explicitly set, the
decoration was added twice on the shader.
v2 (changes after Jonh Kessenich first review)
* Simplified by just removing the firs assignment
* Removed assert
including SPV generation using SPV_EXT_fragment_invocation_density.
This is an alias of the functionality in SPV_NV_shading_rate, and thus in some
cases we can only have one set of the tokens present (switch statements), so
we have picked the EXT version. This required updating the expected test
results for SPV_NV_shading_rate.
Also updated the known-good for spirv-headers so that the validator in
spirv-tools knows about the new extension.
This change adds unary conversion folding when the source is a constant.
This fixes an ISV issue whereby:
```
const float16_t f = float16_t(42.0);
```
Wouldn't compile because the conversion operator would always produce an
EvqTemporary when it could have produced an EvqConst.
I've also added a test case that proves out that all basic-type to
basic-type conversions work.
