Pull Request resolved: #9096 ## Context In some cases, a shader can be compiled successfully with `glslc`, but if an optimization flag such as `-O` or `-Os` is used, the compilation will fail with a message similar to ``` internal error: compilation succeeded but failed to optimize: Invalid use of 8- or 16-bit result\n %133 = OpExtInst %half %1 Pow %125 %132 ``` Which will cause the shader compilation script to fail. This diff introduces a check that if `glslc` complains about not being able to optimize the SPIR-V, then retry compilation without optimization arguments. ghstack-source-id: 271044834 @exported-using-ghexport Differential Revision: [D70906097](https://our.internmc.facebook.com/intern/diff/D70906097/)
