b035ec4a9c * add some DEBUG statements 
* Properly compile this:

struct a {};
int test() {
  struct a b[2];
  if (&b[0] != &b[1])
    abort ();
  return 0;
}

to 'return 0', not abort().

4134789c8f CopyFromReg produces two values. Make sure that we remember that both are 
legalized, and actually return the correct result when we legalize the chain first.

fadcc07232 Remove this code as it is currently completely broken and unmaintained. 
If needed, this can be resurrected from CVS.

Note that several of the interfaces (e.g. the IPModRef ones) are supersumed
by generic AliasAnalysis interfaces that have been written since this code
was developed (and they are not DSA specific).

b7a64c49f0 Do not return true from isSized for things without a size (like functions and 
labels) even though they are concrete.  This fixes the DSA regressions from
last night.

766ad3378c This giant patch speeds up Type::isSized(). Before, this would have to search 
large nested types over and over again to determine if they are sized or not.
Now, isSized() is able to make snap decisions about all concrete types, which
are a common occurance (and includes all primitives).

On 177.mesa, this speeds up DSE from 39.5s -> 21.3s and GCSE from
13.2s -> 11.3s, reducing gccas time from 80s -> 61s (this is a debug build).

DSE and GCSE are still too slow on this testcase, but this is a simple
improvement.
