    Eliminate a spill in concatstrings.
    Provide bounds elim hints in runetochar.
    No significant benchmark movement.
    
    Before:
    "".runetochar t=1 size=412 args=0x28 locals=0x0
    "".concatstrings t=1 size=736 args=0x30 locals=0x98
    
    After:
    "".runetochar t=1 size=337 args=0x28 locals=0x0
    "".concatstrings t=1 size=711 args=0x30 locals=0x90
