Summary: Assert problems when running Jigsaw

Initial Comment:
There're two places always repeatable:
1. In ia32_o3_jit/flow_graph_dom.cpp,
void Flow_Graph::build_dom_tree(){
...
assert(v != -1); //RC-2 Line No.780
...
}
2. In ia32_o3_jit/ir.h:
class Operand {
...
unsigned bv_position() { assert(bvp != (unsigned)-1); 
return bvp; } //RC-2 Line No.107
...
}
Only if I comment out these two assertions could 
Jigsaw run, but I don't know the side-effect.
There's a place occurring occasionally:
3. In gc/generation.cpp:
bool Generation::is_address_in_my_generation(void 
*p_addr){
...
assert(0);
...
}
I noticed that this function only valid when GC_DEBUG 
> 0.

It's hard to be reproduced now. I have to pend it.

Gansha,

Turn off these two asserts is dangerous! I'll help you to 
check the O3 codes when I have time.
