[PATCH] [test-suite] Add test for basic correctness of frame lowering

[Renato Golin]

Hi Kristof,

I haven't looked in detail what the whole code does, but I can see how it stress the stack and how the test works, roughly. As this is in a new directory, it'll be easy to disable on targets where it doesn't work yet, or on compilers that don't support.

Apart from my comment, I think this is a good addition to the test-suite.

cheers,

This is a bit too generic. I'd add AArch64, maybe ARM, but not enable for everything before making sure all UnitTests work on all platforms we run the test-suite.
