`evalBind` will add a `PostStore` point if not given.
IMO, the initializer list here is just to make the assignment, just like `T
test = {1};`, which has an AST structure of
```
DeclStmt 0x55977c889f98 <col:14, col:20>
`-VarDecl 0x55977c889e80 <col:14, col:19> col:16 t 'T':'T' listinit
`-InitListExpr 0x55977c889f50 <col:17, col:19> 'T':'T'
`-IntegerLiteral 0x55977c889ee8 <col:18> 'int' 1
```
The `DeclStmt` here will use the `PostStore` point and wrap it with a
`PostStmt` of `DeclStmt`.
So, a `PostStore` point here makes sense to me.
Besides, in the original `else` branch below, node `Pred` has a PostStmt point
of CXXConstructExpr, which is also different from the `PostInitializer`.
And the `PostInitializer` point is used to notice the diagnostic system that a
field assignment is here.
However, this can be done with the `PostStore` assigned with `evalBind`.
So, I think adding a `PostInitializer` here for the `evalBind` may not be
necessary.
I am not very familiar with program points. If I get it incorrectly, I will
correct this in the next submission.
