ab43beefab x86inc: Drop SECTION_TEXT macro 
The .text section is already 16-byte aligned by default on all supported
platforms so `SECTION_TEXT` isn't any different from `SECTION .text`.

04581c8c77 x86: yasm: Use complete source path for macro helper %includes 
This is more consistent with the way we handle C #includes and
it simplifies the build system.

ca844b7be9 x86: Use consistent 3dnowext function and macro name suffixes 
Currently there is a wild mix of 3dn2/3dnow2/3dnowext.  Switching to
"3dnowext", which is a more common name of the CPU flag, as reported
e.g. by the Linux kernel, unifies this.

The calling convention only allows 4 non-stack parameter, with each
float or int register being skipped if not used.

c73d99e672 Separate format conversion DSP functions from DSPContext. 
This will be beneficial for use with the audio conversion API without
requiring it to depend on all of dsputil.
