a532573cf9 New Windows Unicode solution, works on XP 
Now uses WriteConsoleW instead of vfwprintf. This is codepage
independent and works on Windows XP.

Doing this also avoids the _O_U8TEXT hack.

Don't use `-mavx2 -maes` in collisions

a5e21d1da6 Abstract xxhsum bench, increase line length 
Uses a table and a loop to reduce copy/paste and allow easy testing of
other hash functions. Create a wrapper and insert it into
g_hashesToBench, and it will automatically be added to the benchmark.

The hash display line has been made longer to actually fit xxHash's
names instead of clipping them. It is also configurable.

Restored XXH_malloc, renamed new XXH_malloc to XXH_alignedMalloc

XXH32_state_t and XXH64_state_t are no longer overaligned.

XXH_alignedMalloc takes any power of 2 alignment between 8 and 128.
Granted, we always call it with 64...

6aa4b03e35 Use createState/freeState in the sanity check 
A malloc alignment bug went unnoticed since all states were allocated on
the stack.

It is a more orthogonal usage and tests the allocation functions.

a0b7df7c03 [BUGFIX] Manually align XXH_malloc to 64 bytes. 
Thanks to @RedSpah for finding this bug!

XXH3_state_t is manually 64-byte aligned on the stack, but not manually
aligned when dynamically allocated.

This caused an issue with where the state was assumed to be aligned
and it caused a segmentation fault.

Now, instead of somewhat pointlessly wrapping malloc and free, we write
a portable routine that overallocates and manually aligns the pointer
to 64 bytes.

There is no point in using posix_memalign or _mm_malloc when our
portability requirements would require this fallback anyways.
