This avoids problems if %4 is the stack pointer
the constraints do not allow %4 to be the stack pointer but gcc 9 may
no longer support specifying such constraints

QP_store is only 8-bit-aligned, so accessing it as uint32_t causes
SIGBUS crashes on sparc.
The AV_RN32/AV_WN32 macros only do unaligned access in the
HAVE_FAST_UNALIGNED case.

This should make no difference but its more correct

Also pulled QP initialization out of inner loop, which removed some redundent code.

Added some dummy fields to PPContext to allow current code to work while
changing the rest of the postprocessing code to support the arrays.

I also increased alignment requirements for some fields in the PPContext struct to
support future avx2 code.

Prefetching functions are defined in postprocess_template using the
RENAME macro so that prefetching is used when available. For x86
targets inline asm is used and the functions are non-empty only for
cpus where prefetching is available. For non x86 targets the gcc bultin
prefetch is used if it is available, otherwise no prefetching is done.

There's still an if, as QP needs to be modified if isColor=0, but it
still removes a unecessary branch.
