Steps to reproduce:

Now it is possible to mention the same arguments in --jitflags= and --args= flags in both test suites ("jstests" and "jit-tests"), i.e. "--jitflags=am,amd --args='-a'". It can be seen from the example that argument '-a' is occurred twice in every test case.


Actual results:

The number of total test cases is 
<the number of tests found> * <the number of comma-separated values in --jitflags>.



Expected results:

In case we run "--jitflags=am,amd --args='-a'", the number of test cases remains minimal, so there is no need to avoid argument duplication.
However, if we run "--jitflags=am,amd --args='-a,-m'", 'am' flags can be eliminated, so the number of test cases can be minimized.

The task is to avoid argument duplication in order to minimize the number of test cases. This has to be implemented for both "jstests" and "jit-test".
