Opened https://github.com/KhronosGroup/SPIRV-Tools/pull/1830 to fix this issue.  The problem is that spirv-opt think that a member of a struct cannot have type void, but it seems to be legal.  I changed spirv-opt to accept this.

It is invalid.  I've opened https://github.com/KhronosGroup/SPIRV-Tools/issues/1831 against the validator.
