ast lists to use new[] instead of vector
...
Because the list is not changed after construction, we do not need
the vector's capacity field. This reduces the size of lists from 48
to 32 bytes.

Introduce a new fish ast
...
This is the first commit of a series intended to replace the existing
"parse tree" machinery. It adds a new abstract syntax tree and uses a more
normal recursive descent parser.
Initially there are no users of the new ast. The following commits will
replace parse_tree -> ast for all usages.
