[ARM] Enable SMLAL[B|T] isel
Enable the selection of the 64-bit signed multiply accumulate instructions which operate on 16-bit operands. These are enabled for ARMv5TE onwards for ARM and for V6T2 and other DSP enabled Thumb architectures. Differential Revision: https://reviews.llvm.org/D30044 llvm-svn: 297809
