Using named define properly documents the code paths.
It also avoids passing additional numbered arguments through
multiple levels of macro templates.
The suffix handling is done by concatenation, like in
other asm functions and avoid having two separate
"cglobal" defines.

This splits the asm function into exact and non-exact version. The exact
version is as fast or faster on newer CPUs (which EXTERNAL_AVX_FAST describes
well) whilst the non-exact version is faster than the exact on older CPUs.
Also fixes yasm compilation which doesn't accept !cpuflags(avx) syntax.

Improved version of VBROADCASTSS that works like the avx2 instruction.
Emulation of vpbroadcastd.
Horizontal sum HSUMPS that places the result in all elements.
Emulation of blendvps and pblendvb.

When using streaming input, it may be possible to see frames that appear
before the current_frame. When these frames are inserted into the
index, the current_frame needs to be updated so it is still pointing
at the same frame.

When the background had an alpha channel, the old code in blend_plane
calculated premultiplied alpha from the destination plane colors instead of the
destination alpha.
Also the calculation of the output alpha should only happen after the color
planes are already finished.
Fixes output of:
ffplay -f lavfi "testsrc2=alpha=32[a];color=black[b];[b][a]overlay[out0]"
