add support for arch specific asm constraints

When evaluating asm operands it must be known if they correspond
to a memory operand or not in order to process/ignore the 'noderef'
attribute.

This is done for operands specified with the common constraints
but not for the machine specific constraints.

So, add support for processing machine specific constraints.
