[PATCH] Add UnitTest to test-suite to check correct handling of large stack alignments

[Kristof Beyls]

Testing this on AArch64 showed that dynamic stack re-alignment hasn't been implemented in the AArch64 backend - i.e. this test fails on AArch64.
I'm implementing support for that in the AArch64 backend - I hope to have a patch up for review soon, after which this test can be committed without breaking the AArch64 bots.
