[PATCH v1 00/20] s390x/tcg: Implement Vector enhancements facility and switch to z14

[David Hildenbrand <david@redhat.com>]

This series adds support for the "Vector enhancements facility" and bumps
the qemu CPU model tp to a stripped-down z14.

I yet have to find a way to get more test coverage - looks like some of
the functions aren't used anywhere yet (e.g., VECTOR FP MAXIMUM), writing
unit tests to cover all functions and cases is just nasty. But I might be
wrong - I'm planning to at least test basic functionality of all new added
instructions.

I have to make excessive use of c macros again to cover different element
sizes (32/64/128bit). Any advise to clean things up are welcome.

This is based on:
    "[PATCH v2 0/9] s390x/tcg: Implement some z14 facilities"
    "[PATCH v2 00/10] softfloat: Implement float128_muladd"
