Roll DEPS. (google#586)

Pick up a fix to SPIRV-Tools that will let us add more spvc tests without
blowing up in debug builds.
The SPIRV-Tools roll itself broke some SPIRV-Cross tests, so we also
have to roll in a new SPIRV-Cross that works with the new SPIRV-Tools.
Update glslang and SPIRV-Headers to stay in sync with the new SPIRV-Cross.
