Log:
Add support for masked load/store_lanes

This patch adds support for vectorising conditional load-lanes and
store-lanes instructions.  This requires new internal functions to
represent the result (IFN_MASK_{LOAD,STORE}_LANES), as well as
associated optabs.

The normal IFN_{LOAD,STORE}_LANES functions are const operations
that logically just perform the permute: the load or store is
encoded as a MEM operand to the call statement.  In contrast,
the IFN_MASK_{LOAD,STORE}_LANES functions use the same kind of
interface as IFN_MASK_{LOAD,STORE}, since the memory is only
conditionally accessed.

The AArch64 patterns were added as part of the previous patch.
