[qemu-s390x] [PATCH RFCv2 0/2] tests/tcg: Vector instruction tests for target/s390x

[David Hildenbrand]

As I currently work on vector instruction support for s390x/tcg, for now
I wrote my tests for kvm-unit-tests, but tests/tcg seems to be a better fit.
The only tricky part is testing interrupt handling, but that also seems to
be possible using some signal hackery.

This is only one test to discuss if the approach make sense. These patches
only work when applied on top of:
    https://github.com/davidhildenbrand/qemu/tree/vx

Before I go ahead and implement more tests, let's clarify if this is the
way to go first.

RFC -> RFCv2:
- Dropped "tests/tcg: Allow targets to set the optimization level"
-- Handle it directly from the Makefile
- Add a test for VECTOR GATHER ELEMENT
- Rework signal handling to work with more than one signal occurrence. Also
  simplify setting the signal handlers a bit.

  tests/tcg: target/s390x: Test VECTOR LOAD GR FROM VR ELEMENT
