AArch64: fall back to DWARF instead of crashing on weird .cfi directives

CodeGen will only produce fixed formwat prologues, but hand-written assembly
can have .cfi directives in any combination they want. This should cause a
fallback to DWARF rather than an assertion failure (or an incorrect compact
unwind if assertions are disabled).
