9fa056ba75 pngdsp x86: use unaligned access
For test images manually generated to contain only up prediction,
timing results:
         8380x3032    255x185
before:   138635       1992
after:    139232       1996

Actually jumping to the proper version depending on the alignment:
8380x3032: 138767

A 0.5% speed improvement for gigantic images is not worth the code
duplication.

Fixes ticket #4148

394d41ee30 Partially revert "Fix png decoding on x86."
This partially reverts commit 58dabf7bf2.
It is no longer necessary to use unaligned mov.
The swapped mov argument fix remains though.

58dabf7bf2 Fix png decoding on x86.
Line sizes are only 8-byte aligned, so use unaliged loads
for add_bytes_l2 pointers.
Increasing the alignment requirement to 16 seemed a bit extreme
(png may be used for rather small sizes).
Also fix a mov that had its arguments swapped, leading
add_bytes_l2 being applied on up to 8 bytes too few.
