d78f85e4 - [GlobalISel] Fix getShuffleDemandedElts input lanes in computeKnownFPClass (#192288)

[GlobalISel] Fix getShuffleDemandedElts input lanes in computeKnownFPClass (#192288) The number of lanes needs to be for the input type, not the return, as they can be different in GISel. This prevents an assert about invalid shuffle mask constant from getShuffleDemandedElts.
