now that loads are in their own table, we can implement
store->load forwarding. This allows EarlyCSE to zap 600 more
loads from 176.gcc.

by their pointer instead of using MemoryValue to wrap it.

Teach EarlyCSE to do trivial CSE of loads and read-only calls.
On 176.gcc, this catches 13090 loads and calls, and increases the
number of simple instructions CSE'd from 29658 to 36208.
