  -----------
  [Hexagon] Order objects on the stack by their alignments (#81280)

This patch sorts stack objects by their alignment value from the largest
to the smallest. If two objects have the same alignment, then they are
sorted by their size from the largest to the smallest. This minimizes
padding and reduces run time stack size.
