@item SAVE_EXPR
FIXME: Describe.
A @code{SAVE_EXPR} represents an expression (possibly involving
side-effects) that is used more than once. The side-effects should
occur only the first time the expression is evaluated. Subsequent uses
should juse reuse the computed value. The first operand to the
@code{SAVE_EXPR} is the expression to evaluate. The side-effects should
be executed where the @code{SAVE_EXPR} is first encountered in a
depth-first preorder traversal of the expression tree.
@item TARGET_EXPR
A @code{TARGET_EXPR} represents a temporary object. The first operand
