FFmpeg/libavcodec/x86/vp9itxfm.asm
Ronald S. Bultje c9e6325ed9 vp9/x86: use explicit register for relative stack references. 
Before this patch, we explicitly modify rsp, which isn't necessarily
universally acceptable, since the space under the stack pointer might
be modified in things like signal handlers. Therefore, use an explicit
register to hold the stack pointer relative to the bottom of the stack
(i.e. rsp). This will also clear out valgrind errors about the use of
uninitialized data that started occurring after the idct16x16/ssse3
optimizations were first merged.
