Handle the synthetic fallthrough sentinel in Sleigh control-flow analysis without indexing past the end of the pcode ops vector. Also fix the aarch32 smoketest flag spelling in CI and keep Nix checks enabled on Darwin so the smoketests run consistently across environments.
Comment out subnormal (0x1) test inputs for fcvtzu/fcvtzs double-to-
64-bit-integer tests on AArch64. LLVM 22 misselects the SIMD form
(fcvtzu d,d) which drops FE_INEXACT on subnormal inputs.

LLVM 16+ changed the resource directory path from lib/clang/<full-version>
(e.g. 15.0.7) to lib/clang/<major> (e.g. 16). Use release_version from
nixpkgs to match the upstream nixpkgs clang wrapper logic (D125860).
