Fix Clang 15 compilation errors
- Clang 15 doesn't support `-fno-ipa-sra` anymore. Do a separate check for `-fno-ipa-sra` support by $KERNEL_CC. - Don't enable `-mgeneral-regs-only` for certain module files. Fix #13260 - Scope `GCC diagnostic ignored` statements to GCC only. Clang doesn't need them to compile the code.
