David Green c9378320d3 [ARM] Lower MVETRUNC to stack operations 
The MVETRUNC node truncates two wide vectors to a single vector with
narrower elements. This is usually lowered to a series of extract/insert
elements, going via GPR registers. This patch changes that to instead
use a pair of truncating stores and a stack reload. This cuts down the
number of instructions at the expense of some stack space.
