ArrayTest does not pass with course compiler + OS libs

[gcpd]

I think at some point the code must have been updated but I found the culprit, in ArrayTest.tst it wasn't running quite long enough to reach the end of the program at 1mil steps but bumping it to 1.25m got it over the line. Obviously if using your own compiler/libs your mileage may vary.

repeat 1250000 {
  vmstep;
}

Steps to reproduce:
- Copy tools/OS/*.vm to projects/12/ArrayTest
- Compile projects/12/ArrayTest/Main.jack with JackCompiler
- Run ArrayTest folder/script with VMEmulator

This is with the "legacy" software suite v2.7
