Some tests in our test suite are unbelievably slow on GCC due to the use of the always_inline attribute. See [1] for more details. This patch introduces the GCC-ALWAYS_INLINE-FIXME lit feature to disable tests that are plagued by that issue. At the same time, it moves several existing tests from ad-hoc `UNSUPPORTED: gcc-12` markup to the new GCC-ALWAYS_INLINE-FIXME feature, and marks the slowest tests reported by the CI as `UNSUPPORTED: GCC-ALWAYS_INLINE-FIXME`.
