Rewrite the code to use linear_asprintf and always flip the
dimensions in place if the element type is an array. The new
code will now (correctly) flip even in the case of unsized arrays.
The flipping is done by swapping the ranges [a, b) and [b, c), as
shown below, with element type int[...] and an array of length 4.
```
+--------------- a: first bracket in the name
| +---------- b: end of the element name
| | +------- c: end of the array name
| | |
int[...][4]$
will be transformed into
int[4][...]$
```
