Implemented intrinsics llvm.variable.length.load and llvm.variable.length.store,
as well as infrastructure for lowering these using new corresponding SDAG nodes.

These intrinsics represent loading and storing vectors with a number of contiguous active lanes given at runtime.
In effect, they specialize masked loads and stores to the case when the mask can instead be specified by a length.

Please see our associated RFC for technical design discussion.
