Sam Parker 2ef3c0dad6 [ARM] bottom-top mul support in ARMParallelDSP
Previously reverted in rL343082.

Original commit message:

On failing to find sequences that can be converted into dual macs,
try to find sequential 16-bit loads that are used by muls which we
can then use smultb, smulbt, smultt with a wide load.
