A64: Remove two TODOs that will not be done.

- For the LDP/STP TODO: The arguments need dereferencing, so using LDP/STP would
  require some additional checks.
- For the constant pools TODO: Unless we need to, there is no benefit from
  trying to generate constant pools more often, as it would likely only pollute
  the I-cache.

Move parenthesized_function_ to ParserBase.

This change is trivial (was probably overlooked when ParserBase was created).
