### Problem
[Similarly to GCC's toolchain](https://lists.gnu.org/archive/html/bug-gnulib/2020-12/msg00001.html), Apple Clang's has extra predefinitions which aren't all defined by Clang.
For instance the following are defined by Apple Clang's preprocessor, but is not defined anywhere by Clang:
- `__ARM_ARCH_8_3__`
- `__ARM_ARCH_8_4__`
- `__ARM_ARCH_8_5__`

### Proposed solution
Define recently introduced predefinitions, such as done for `__ENVIRONMENT_OS_VERSION_MIN_REQUIRED__` with https://github.com/llvm/llvm-project/commit/c8e2dd8c6f490b68e41fe663b44535a8a21dfeab.

Problem
Similarly to GCC's toolchain, Apple Clang's has extra pre-processor definitions which aren't all defined by Clang.
For instance the following are defined by Apple Clang's preprocessor, but is not defined anywhere by Clang:
__ARM_ARCH_8_3____ARM_ARCH_8_4____ARM_ARCH_8_5__All Apple Clang pre-processor definitions
