avoids passing around the extra argument among all the macros it uses

This allows emulated_edge_mc_sse() and gmc_sse() to be used under
AV_CPU_FLAG_SSE.

This allows sharing them between multiple .asm files.

This allows using it in libswscale/ also.

This format is still used by e.g. OS/2.

Fix emu_edge_v_extend_15 to be <128 bytes on Win64, by being more strict
on the size of registers and which registers are being used for operations
where multiple are available. This fixes segfaults in emulated_edge()
function calls on Win64.

This will be beneficial for use with the audio conversion API without
requiring it to depend on all of dsputil.

Modify the asm accordingly.
GLOBAL is now no longoer necessary for PIC-compliant loads.

29-105% faster apply_filter, 6-90% faster ape decoding on core2
(Any x86 other than core2 probably gets much less, since this is mostly due to ssse3 cachesplit avoidance and I haven't written the full gamut of other cachesplit modes.)
9-123% faster ape decoding on G4.
