07eb7e20af ppc: swscale: rework yuv2planeX_altivec()
This gets rid of the variable-length scratch buffer by filtering 16
pixels at a time and writing directly to the destination.  The extra
loads this requires to load the source values are compensated by not
doing a round-trip to memory before shifting.

b64a72e1b2 yuv2rgb: handle line widths that are not a multiple of 4.
This introduces support for width%4==2 in addition to width%4==0. For
odd widths, some more checks are needed, since the current code always
handles two luma items in a row, thus there is a possibility of an
overread by one.

90540c2d5a x86: swscale: fix fragile memory accesses
To access data at multiple fixed offsets from a base address, this
code uses a single "m" operand and code of the form "32%0", relying on
the memory operand instantiation having no displacement, giving a final
result of the form "32(%rax)".  If the compiler uses a register and
displacement, e.g. "64(%rax)", the end result becomes "3264(%rax)",
which obviously does not work.

Replacing the "m" operands with "r" operands allows safe addition of a
displacement.  In theory, multiple memory operands could use a shared
base register with different index registers, "(%rax,%rbx)", potentially
making more efficient use of registers.  In the cases at hand, no such
sharing is possible since the addresses involved are entirely unrelated.

After this change, the code somewhat rudely accesses memory without
using a corresponding memory operand, which in some cases can lead to
unwanted "optimisations" of surrounding code.  However, the original
code also accesses memory not covered by a memory operand, so this is
not adding any defect not already present.  It is also hightly unlikely
that any such optimisations could be performed here since the memory
locations in questions are not accessed elsewhere in the same functions.

This fixes crashes with suncc.

118bd609f0 Optimized unscaled yuvp9/yuvp10 -> yuvp16 conversion.
About 30% faster on 32 bit Atom, 120% faster on 64 bit Phenom2.
This is interesting because supporting P16 is easier in e.g.
OpenGL (can misuse support for any 2-component 8 bit format),
whereas supporting p9/p10 without conversion needs a texture
format with at least 14 bits actual precision.
The shiftonly == 0 case is not optimized since the code is more
complex and the speed gain less obvious.
