[Bug middle-end/21858] [4.1 Regression] ICE in compare_values, at tree-vrp.c:301

Confirmed, reduced testcase:
unsigned int dsdblm_GetBlockAddress();
void error_LocalAssert(void);
int dsdblm_CreateBlock(unsigned int address)
{
   address = dsdblm_GetBlockAddress();
   if (address >= (void*)0x00020000)
     error_LocalAssert();
   return address;
}
This is either a front-end bug or a fold bug.
