v2:
https://lore.kernel.org/qemu-devel/20240409050302.1523277-1-richard.hender...@linaro.org/
Disconnect fpstate from sigframe, just like the kernel does.
Return the separate portions of the frame from get_sigframe.
Alter all of the target fpu routines to access memory that
has already been translated and sized.
Changes for v3:
- Address review issues (bonzini).
- Rebase.
