[ARM] Add qadd lowering from a sadd_sat
This lowers a sadd_sat to a qadd by treating it as legal. Also adds qsub at the same time. The qadd instruction sets the q flag, but we already have many cases where we do not model this in llvm. Differential Revision: https://reviews.llvm.org/D68976 llvm-svn: 375411
