When we create a new Conv node in combo's exchange_leader(), this irn has no node_t.
This is ok, replace the original node in a post walker.
However, as the new node has a visited count of 0 it might be revisited
again.
Fix this by copying the visited count.

This fixes testsuite/opt/fehler179.c

cgana() returns now the lenght of the free_methods array instead of
setting a passed pointer.

We must differentiate between the value type and the va_arg type ...

[r28262]

va_arg must be used with int instead of char/short.  All integer arguments are at least promoted to int.
