Eli Friedman 02e737b08e Move "atomic" and "volatile" designations on instructions after the opcode 
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.

Nick Lewycky 32966aed9d Teach DAE that even though it can't modify the function signature of an 
externally visible function, it can still find all callers of it and replace
the parameters to a dead argument with undef.
