    [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.
