  [clang][test] Add more tests for __builtin_clear_padding (#205813)

Follow-up to https://github.com/llvm/llvm-project/pull/201102 which
fixed Clang's `__builtin_clear_padding` treatment of unnamed bitfields.

This patch adds some more test coverage (more layouts, and verifies IR).

Used Claude to generate the layouts. Manually ran
`llvm/utils/update_cc_test_checks.py` to generate the `CHECK` directives
and confirmed that the bit-masks in the IR match the expected
`__builtin_clear_padding` behaviour.
