      [Liftoff] Don't force unrelated stack slots into registers · 1cec66d3
      Clemens Hammacher authored
      When initializing the stack state at a merge point, don't force all
      stack slots into registers. Allow constants to stay constants as long
      as they are not part of the merge. Otherwise we might break assumptions
      of outer blocks which then try to merge a register into a constant and
      fail.
      Also, add some documentation to {InitMergeStackSlot} to document the
      intent of the implementation.
