Added a simple fake_sigreturn testcase which places a valid sigframe on a non-16 bytes aligned SP. fake_sigretrun() helper function has been patched accordingly to support placing a sigframe on a non-16 bytes aligned address. Expects a SIGSEGV on test PASS.
Adds also a test TODO lists holding some further test ideas.

Re-added this text after fixing the forced misaglinment procedure in fake_sigreturn() itself: require a ZERO alignment and you'll get your sigframe placed on a misaligned SP (2-bytes off the 16-align)

When this test was re-added in V3, the related .gitignore was missed. It will go in V4
Ack, or otherwise try switching to using wildcards in .gitignore as suggested in my reply to patch 4.
