[foreign] RFR 8222739: Port CallingSequenceTest to Windows

[Jorn Vernee]

Hi,

I have ported the SysV CallingSequenceTest to Windows (and fixed a 
little bug in the process as well :) ).

In an effort to reduce code duplication in the tests, I have create a 
testing utility that automatically checks that the number of argument 
classes is correct. I've updated the existing SysV CallingSequenceTest 
to use this utility as well. You just have to specify the argument, and 
the expected bindings e.g. :

     new Verifier(new CallingSequenceBuilderImpl(null))
             .arg(Layout.of("[u64u64u64u64]"),
                     binding(STACK_ARGUMENT_SLOT, 0),
                     binding(STACK_ARGUMENT_SLOT, 8),
                     binding(STACK_ARGUMENT_SLOT, 16),
                     binding(STACK_ARGUMENT_SLOT, 24))
             .check(false);

Specifies 1 argument with the layout "[u64u64u64u64]", which is expected 
to have 4 bindings.

Please review the following.
