Yasm creates an implicit unaligned text section if "struc" is used
outside of any section:
http://tortall.lighthouseapp.com/projects/78676-yasm/tickets/247
Since yasm only honors the "align" annotation on the first declaration
of a section, this implicit text section causes all text section
alignments to be ignored. Also fixes a yasm warning about it agnoring
alignment.

This is required to handle clobbering of XMM registers on Win64
correctly. Fixes FFT and all tests depending on FFT on Win64.

This is to avoid split asm sections that attempt to preserve some
registers between sections.

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

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.

Use the new x86inc features to support 64-bit Windows on all non-x264 nasm
assembly code as well.

This fixes linking shared libavcodec, since the linker doesn't allow
text relocations in shared libraries under Darwin/x86_64.

It contains optimizations that are not specific to i386 and
libavutil uses this naming scheme already.

c is 1.9x faster than previous c (on various x86 cpus), sse is 1.6x faster than previous sse.
