5797ed66 - [GISel][SDAG] Avoid push_back in loops for some shuffle mask handling. (#119434)

[GISel][SDAG] Avoid push_back in loops for some shuffle mask handling. (#119434) Each call to push_back contains a check to see if the vector needs to grow. Using resize or giving the size to the constructor can reduce the number of checks for growing.
