[PATCH 11/18] asm: keep using struct asm_operand during linearization

[Luc Van Oostenryck <luc.vanoostenryck@xxxxxxxxx>]

In linearize_asm_statement(), the functions asm_add_{input,output}()
are given the ASM operand 'name', 'constraint' & 'expression'
as argument. However, it's much simpler to simply give the whole
struct asm_operad.
