SPIRV-Tools and tests: Update to location-validation in SPIRV-Tools.

This introduces five new "Validation failures": - baseResults/hlsl.semantic.vert: issue with gl_ClipDistance/CullDistance - baseResults/spv.430.vert: issue gl_ClipDistance - baseResults/spv.450.tesc: still unknown - baseResults/spv.dataOut.frag: gl_FragData should not be supported, problem with front end - baseResults/spv.meshShaderPerViewUserDefined.mesh: seems okay, maybe a problem with SPIRV-Tools
