[f-cpu] Are 8 bits SIMD mode usefull ?

[nico <nicolas.boulay@ifrance.com>]

Just a stupid question : is 8 bits integer mode usefull ?

"Char" C type are going to be 16 bits (unicode) or even 32. 3D are going
in floating point even in the GPU. Gimp use 16 bit per channel (in
certain mode, even more ?). 

8 bits are really tricky to use to avoid overflow/underflow during
calculation, that's why people try to use bigger number.

Is that clever to enable such mode in a "futur" cpu which will be
a reality in 2 years ?

my 2 cents.
