Fix stack-overflow in `lhs_expression`.

Currently when parsing `*` and `&` we recursively call into ourselves to
process the tokens. This can cause stack issues if there are an
excessive number of `*`s and `&`s.

This Cl changes `lhs_expression` to generate a list of UnaryOps to be
applied and does not recursively call `lhs_expression`.
