[Qemu-devel] [PATCH] tcg/i386: fix unsigned vector saturating arithmetic

[Mark Cave-Ayland]

Due to a cut/paste error in the original implementation, the unsigned vector
saturating arithmetic was erroneously being calculated as signed vector 
saturating
arithmetic.

Fixes: 8ffafbcec2 ("tcg/i386: Implement vector saturating arithmetic")
