The indexed variant of vfmal.f16 and vfmsl.f16 instructions use the uppser bits of the indexed operand to store the index (1 bit for the double variant, 2 bits for the quad). This limits the usable registers to d0 - d7 or s0 - s15. This patch enforces this limitation. Differential Revision: https://reviews.llvm.org/D59021 llvm-svn: 355707
