[PATCH] D121109: [AArch64] Add cost model for llvm.get.active.lane.mask intrinsic

[David Sherwood via Phabricator via llvm-commits]

- Moved all of the cost calculation into BasicTTIImpl.h and tried to estimate the cost more formally for the case where we expand the intrinsic. The expansion costs look way over the top to be honest, but I guess we can refine those later if necessary.
