Avoid generating array names in solver builders that could accidently collide
If an array name ended with a number, adding a number-only suffix could
generate the same name used as part of the solvers.

In the specific testcase `val_1` became solver array `val_111` which
collided with array `val_11` that became `val_111` as well.

Using an `_` as prefix for the suffix, solves that problem in general,
i.e. `val_1` becomes `val_1_11` and `val_11` becomes `val_11_1`.

Fixes #1668
