[lworld] RFR: 8374115: [lworld] test_classPrinter.cpp fails with Valhalla [v2]

[Casper Norrbin]

> Hi everyone,
> 
> `test_classPrinter` tests `classPrinter` using regex to verify that the output matches the expected format.  
> The `print_classes` test includes (among other things) printing the class details for `java.lang.Integer`. 
> 
> On mainline, the static fields are printed like this:
> 
> Java mirror oop for java/lang/Integer: java.lang.Class 
> {0x0000000efc0427a0} - klass: 'java/lang/Class' - flags: 
>  - ---- fields (total size 19 words):
> ...
> - ---- static fields (2):
>  - public static final 'MIN_VALUE' 'I' @136  -2147483648 (0x80000000)
>  - public static final 'MAX_VALUE' 'I' @140  2147483647 (0x7fffffff)
> ...

> With the Valhalla changes, the output now includes `value`:

> When printing fields' access flags, we now also print `identity`/`value` depending on whether a field has identity. Most fields (including `MIN_VALUE`) do not have identity and therefore show `value`. The existing regex did not account for this new print, making the test fail. I have updated it accordingly and the test now passes again.
