Use zero-call-used-regs=used with Apple compilers.V_9_4
Apple's versions of clang have version numbers that do not match the
corresponding upstream clang versions. Unfortunately, they do still
have the clang-15 zero-call-used-regs=all bug, so for now use the value
that doesn't result in segfaults. We could allowlist future versions
that are known to work. bz#3584 (and probably also our github CI
failures).
