    [TTI] New target hook emitGetActiveLaneMask · 7480ccbf
    Sjoerd Meijer authored
    This is split off from D79100 and adds a new target hook emitGetActiveLaneMask
    that can be queried to check if the intrinsic @llvm.get.active.lane.mask() is
    supported by the backend and if it should be emitted for a given loop.
    
    See also commit rG7fb8a40e and its commit message for more details/context
    on this new intrinsic.
