Enable CI on rewrite branch using new 'ci' target

ChangeLog:

	* .github/workflows/Clang.yml: Add rewrite branch. Use 21 and
	22. Pull from latest cplusplus-ci/clang. Build ci target.
	* .github/workflows/GCC.yml: Likewise, except for gcc16 only.
	* Makefile.common: Build with
	-D_GLIBCXX_SIMD_CONSTEVAL_BROADCAST. Filter out misc test (for
	now).
	* Makefile.more: Add ci target.
	* Makefile: Add ci to more_checks.
