## Message

```
stage2 parser: split off some SuffixOp AST nodes into separate tags

These SuffixOp nodes have their own ast.Node tags now:
 * ArrayInitializer
 * ArrayInitializerDot
 * StructInitializer
 * StructInitializerDot

Their sub-expression lists are general-purpose-allocator allocated
and then copied into the arena after completion of parsing.

throughput: 72.9 MiB/s => 74.4 MiB/s
maxrss: 68 KB => 72 KB

The API is also nicer since the sub expression lists are now flat arrays
instead of singly linked lists.

```
