    asm-emit-time IND_STATIC elimination
    
    When a new closure identifier is being established to a
    local or exported closure already emitted into the same
    module, refrain from adding an IND_STATIC closure, and
    instead emit an assembly-language alias.
    
    Inter-module IND_STATIC objects still remain, and need to be
    addressed by other measures.
    
    Binary-size savings on nofib are around 0.1%.
