See sample vp90-2-14-resize-fp-tiles-16-8-4-2-1.webm from the vp9 test
vector set which reproduces the issue. This probably costs a few cycles,
but I don't think there's an easy way to workaround that.

When the decoder is deactivated, the x86-optimized versions are
not compiled, resulting in a link error.
The C version is unaffected, as it is part of the idctdsp
subsystem.

The main difference consists in renaming properly labels, and
letting yasm select the gprs for skipping 1D transforms.

Commit message partly taken from carl
fixes a compilation
error in mlpdsp_init.c with -fstack-check and some gcc compilers (I
reproduced the issue with gcc 4.7.3) by simplifying the code.

The 3*stride value stored in r3src can be loaded much later,
so use r3src instead of a dedicated gpr when possible.

The second stride is always the internal buffer one, MAX_PB_SIZE (times 2 to
get the value in bytes).

The width parameter is now completely at the back, and actually
never used. This helps understanding the actual parameter list.

The later was fixed to work with the DSP.

pb_eo must be handled as a rip relative address for MSVC64, so an
intermediate register is needed. Should fix link failures.
