linux-user: i386/signal: support FXSAVE fpstate on 32-bit emulation
Linux can use FXSAVE to save/restore XMM registers even on 32-bit
systems. This requires some care in order to keep the FXSAVE area
aligned to 16 bytes; for this reason, get_sigframe is changed to
pass the offset into the FXSAVE area rather than the full frame
size.
