Akira Hatanaka f53b0403f8 [AArch64] Define subtarget feature strict-align. 
This commit defines subtarget feature strict-align and uses it instead of
cl::opt -aarch64-strict-align to decide whether strict alignment should be
forced.

Lang Hames 903338511b [AArch64] Teach AArch64TargetLowering::getOptimalMemOpType to consider alignment 
restrictions when choosing a type for small-memcpy inlining in
SelectionDAGBuilder.

This ensures that the loads and stores output for the memcpy won't be further
expanded during legalization, which would cause the total number of instructions
for the memcpy to exceed (often significantly) the inlining thresholds.
