Apply commands llvm-spirv -to-binary global_var_host_access.spt and then llvm-spirv -to-text global_var_host_access.spv -o global_var_host_access.spv.spt. Output global_var_host_access.spv.spt is

1. GlobalVariableDecorationsINTEL is added
2. In Decorate 5, ReadINTEL "IntVarName" are missing
3. Decorate 9 is missing
