of the instruction.
Note that this change affects the existing non-atomic load and store
instructions; the parser now accepts both forms, and the change is noted
in the release notes.

invalidated by stores, so they can be handled as 'simple'
operations.

elimination as well. This deletes 60 stores in 176.gcc
that largely come from bitfield code.

store->load forwarding. This allows EarlyCSE to zap 600 more
loads from 176.gcc.

On 176.gcc, this catches 13090 loads and calls, and increases the
number of simple instructions CSE'd from 29658 to 36208.

Teach it to CSE the rest of the non-side-effecting instructions.
