0e5200ad - Refactor target_compile_options into torch_compile_options (#29730)

Refactor target_compile_options into torch_compile_options (#29730) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/29730 Back in the day, Caffe2 had a good idea: instead of spattering target_compile_options all over the codebase, define a helper function which sets all the options for a target. This is especially helpful if I want to split libtorch.so into libtorch_cpu.so and libtorch_cuda.so; I need a way to easily apply options to multiple targets. A shared helper function is just the ticket. I moved every target_compile_options call in caffe2/CMakeLists.txt that didn't seem target dependent (exclusions included OpenMP flags, API-related macros, ONNX related macros and HIP flags) into torch_compile_options. I slavishly preserved the structure: there's a nearly redundant WERROR if() in the output but I preserved it. There is one thing I don't like about this, which is that now the compile options are off in a random directory that no one would expect. But c'est la vie... Signed-off-by: Edward Z.
