<pre>Leaving it broken for v7 and v8 is not a sufficient fix. This issue has been
affecting musl libc for a long time. For setjmp/longjmp, we need to be able to
use forms of vstmia/vldmia that:
1. Do not cause the object file to be ABI-tagged as needing VFP.
2. Assemble even on targets that don't have VFP.
3. Assemble to ARM or Thumb2 properly depending on target.
Right now we're stuck with using .word to meet requirements 1 and 2, which is
utterly awful, and trying to find a suitable way to add support for Thumb2-only
code generation.</pre>
