Fixes #112270 Completed ACs: - `-res-may-alias` clang-dxc command-line option added - It inserts and sets a module metadata flag `dx.resmayalias` to 1 - Shader flag set appropriately: - The flag IS NOT set if DXIL Version <= 1.6 OR the command-line option `-res-may-alias` is specified - Otherwise the flag IS set when: - DXIL Version > 1.7 AND function uses UAVs, OR - DXIL Version <= 1.7 AND UAVs present globally - Add tests - Tests for Shader Models 6.6, 6.7, and 6.8 corresponding to DXIL Versions 1.6, 1.7, and 1.8 - Tests (`res-may-alias-0.ll`/`res-may-alias-1.ll`) for when the module metadata flag `dx.resmayalias` is set to 0 or 1 respectively - A frontend test (`res-may-alias.hlsl`) for testing that that the command-line option `-res-may-alias` inserts `dx.resmayalias` module metadata correctly
