Change #264260

swscale/x86/output: Make xmm functions usable even without aligned stack
x86-32 lacks one GPR, so it needs to be read from the stack.
If the stack needs to be realigned, we can no longer access
the original location of one argument, so just request a bit
more stack size and copy said argument at a fixed offset from
the new stack.
