[Bug optimization/9566] Inline function produces much worse code than manual inlining.

Here is valid (correctly initializing "a") code which shows the problem on the tree-ssa and on the 
mainline:
struct A {
  char const* src;
  char* dest;
  void copy() { *++dest = *++src; }
};

void g1(A *b) {
  A a = *b;
  for(int i = 0; i < 10; ++i)
    a.copy();
}

void g2(A* b) {
  A a = *b;
  for(int i = 0; i < 10; ++i)
    *++a.dest = *++a.src;
}
