//===---------------------------------------------------------------------===//
set_local and store instructions have a return value. We should (a) model this,
and (b) write optimizations which take advantage of it. Keep in mind that
many set_local instructions are implicit!
//===---------------------------------------------------------------------===//
Load and store instructions can have a constant offset. We should (a) model
this, and (b) do address-mode folding with it.
//===---------------------------------------------------------------------===//
Br, br_if, and tableswitch instructions can support having a value on the
expression stack across the jump (sometimes). We should (a) model this, and
(b) extend the stackifier to utilize it.
