I think the presence of `-munaligned-access` or `-mno-strict-align` also needs
to be considered here.
Looking at `clang/lib/Driver/Toolchains/Arch/AArch64.cpp`, it looks like the
last of these options is the one which takes effect:
```
if (Arg *A = Args.getLastArg(
options::OPT_mstrict_align, options::OPT_mno_strict_align,
options::OPT_mno_unaligned_access, options::OPT_munaligned_access)) {
if (A->getOption().matches(options::OPT_mstrict_align) ||
A->getOption().matches(options::OPT_mno_unaligned_access))
Features.push_back("+strict-align");
```
I'd recommend using the same logic here.
