Thiago Macieira f7a7a49f92 Fix the AVX2 ARGB->ARGB64 conversion code 
Commit c8c5ff19de introduced the solution
as a simple scaling up of the code in qdrawhelper_sse4.cpp, but it's bad
due to the way that the 256-bit unpack instructions work: the unpack-low
instruction unpacks the lower half of each half of the 256-bit register.
So we fix it up by inserting a permute4x64 that swaps the middle two
quarters of the 256-bit register (permute8x32 requires a __m256i
parameter, instead of an immediate).

This introduces an instruction that costs 3 cycles in each loop, but
since the AVX2 code has double the throughput compared to SSE4 code, it
should still be faster.

This problem does not affect the ARGB->ARGB32 code because that repacks
at the end.
