These patches fix a problem with the linearization of asm statements
with output memory operands. These operands need to have their address
generated before the asm instruction but was generated after it.

Note: the problem wasn't visible when the address was a symbol
      because the OP_SYMADDR producing the address is simplified
      away at some later stage with the symbol directly handled
      by the memory operation.

Luc Van Oostenryck (3):
  asm: add testcase for problem with output addresses
  asm: factor out add_asm_rule() from add_asm_{in,out}put()
  asm: output *memory* operands need their address as *input*
