This PR fixes illegal use of OpConstantComposite with non-constant constituents. The test attached to the PR is able now to satisfy `spirv-val` check. Before the fix SPIR-V Backend produced for the attached test case a pattern like ``` %a = OpVariable %_ptr_CrossWorkgroup_uint CrossWorkgroup %uint_123 %11 = OpConstantComposite %_struct_6 %a %a ``` so that `spirv-val` complained with ``` error: line 25: OpConstantComposite Constituent <id> '10[%a]' is not a constant or undef. %11 = OpConstantComposite %_struct_6 %a %a ```
