LoadNamedFeedback(int slot) const {
As discussed offline: Haveing to deal with IC-related data structures
here is a smell. Can we instead just define a vecotr-slot-pair in
js-operators.h that is a pure data container without logic?
nit: This needs a comment. Also we should make it private (by placing it
further down).

src/compiler/ast-graph-builder.h:93: Node*
BuildVariableLoad(VariableProxy* proxy, BailoutId bailout_id,
Either all the BuildVariableFoo helpers should work on Variable or on
VariableProxy, this arbitrary dichotomy smells.
As discussed offline: It might be better to instead pass the
vector-slot-pair as an argument.

vector_;
nit: Let's not start caching handles yet, this seems like premature
optimization.

KeyedLoadICFeedbackNode feedback(Handle<TypeFeedbackVector>::null(), 0);
nit: Please move this out of the for-each loop (to around line 80) for
readability.
