78b5c97d3e Convert ff_imdct_half_sse() to yasm.
This is to avoid split asm sections that attempt to preserve some
registers between sections.

2966cc1849 Update x264asm header files to latest versions.
Modify the asm accordingly.
GLOBAL is now no longoer necessary for PIC-compliant loads.

3d05c1fbec Make the jump-table section-relative for x86_64 with PIC enabled.
This allows to get rid of the macho64 specific hack that moves them
to rodata (with worse cache behaviour) and avoids textrels which
e.g. Gentoo does not allow for x86_64 libraries.

3f87f39cb8 Update x264 asm code to latest to add support for 64-bit Windows.
Use the new x86inc features to support 64-bit Windows on all non-x264 nasm
assembly code as well.
Patch by John Adcock, dscaler.johnad AT googlemail DOT com.
Win64 changes originally by Anton Mitrofanov.
x86util changes mostly by Holger Lubitz.

b6188c5a55 Put dispatch_tab in the rodata section for macho64.
This fixes linking shared libavcodec, since the linker doesn't allow
text relocations in shared libraries under Darwin/x86_64.

Based on a patch by Art Clarke (aclarke xuggle com)

a6493a8fbd Rename libavcodec/i386/ --> libavcodec/x86/.
It contains optimizations that are not specific to i386 and
libavutil uses this naming scheme already.
