babl: babl-fish-path improve portability for ppc
Quoting his explaination for why this fixes things (the other half of
the same function was already portable.)
"This breaks on PowerPC 32-bit, because the calling convention for
passing a union is to pass a pointer to a temporary copy of the union.
This pointer isn't as a function pointer. On some other platforms, the
call would just copy the union, which is like copying the function
pointer. On all platforms, the compiler doesn't check the type, because
babl_conversion_new() has a va_arg(3) prototype."
Portabilitiy issue figured out by George Koehler, This fixes issue #24.

Add AVX2 conversions from Y float, YA float, RGB float, and RGBA

The conversions use a lookup table, similarly to the two-table
conversions, indexed using AVX2's 256-bit gather instruction, which
allow us to process 8 floats at once. Over here, this conversion
is ~5x faster than the SSE conversions.
Note, however, that unlike two-table, we don't use a second
"feedback" table to correct the result, leading to an off-by-one
conversion error with a probability of ~0.1%, using a 2^16-element
table. This error rate is low enough for babl to use the
conversion, but might still be a bit too high regardless; it can be
further reduced with a bigger table.
