  Log Message:
  -----------
  [clang][test] Add `%clang_cc1_cg_arm64_neon` substitution (#188547)

Add a LIT substitution `%clang_cc1_cg_arm64_neon` expanding to:
```python
  clang -cc1 -internal-isystem <path> \
    -triple arm64-none-linux-gnu \
    -target-feature +neon -o -
```
This invocation is repeated across multiple tests. Introducing a
substitution reduces duplication, shortens RUN lines, and ensures
consistency across `clang -cc1` invocations.

Shorter RUN lines also make test-specific flags easier to spot.
