- Set the shader flag `DisableOptimizations` based on `optnone` attribute of shader entry functions. - Add DXIL Metadata Analysis pass as pre-requisite for Shader Flags pass to obtain entry function information collected therein. - Named module metadata `dx.disable_optimizations` is intended to indicate disabling optimizations (`-O0`) via commandline flag. However, its intent is fulfilled by `optnone` attribute of shader entry functions as implemented in a recent change, and thus not needed. Delete generation of named metadata and corresponding test file `disable_opt.ll`. - Add tests to verify correctness of setting shader flag. Closes #112263
