This series adds support for the "Vector enhancements facility" and bumps
the qemu CPU model to a stripped-down z14.
I tested most vector FP instructions by generating random instructions
and vectors, comparing the result with results on actual hardware. I did
not test instructions/instruction variants with (partial) undeterministic
behavior and exception handling.
Linux' also seems to boot/work fine with it. Howeever, while testing this
series I noticed that Linux checks for the wrong facility bit - see [1].
I tested by temporarily faking availability of the "wrong" facility bit.
[1] https://lkml.kernel.org/r/20210503121244.25232-1-david@redhat.com
v2 -> v3:
- "s390x/tcg: Fix FP CONVERT TO (LOGICAL) FIXED NaN handling"
-- Keep proper signal handling in the VECTOR variants
- "s390x/tcg: Simplify vop64_2() handling"
-- uint64_t se -> bool se
- "s390x/tcg: Implement VECTOR FP (MAXIMUM|MINIMUM)"
-- Drop special cases when both values are infinity
-- Simplify cases when both values are zero
-- Simplify dcmask handling
-- uint64_t se -> bool se
- "linux-user: elf: Prepare for Vector enhancements facility"
-- Added to properly indicate the new elf capability
v1 -> v2:
- Too much changed to spell it out explicitly. Mostly addressed feedback
from Richard, a couple of bugfixes found while testing, and some
simplifications/cleanups.
- Rebased on top of Richard's softfloat rework

In case we encounter a NaN, we have to return the smallest possible
number, corresponding to either 0 or the maximum negative number. This
seems to differ from IEEE handling as implemented in softfloat, whereby
we return the biggest possible number.
While at it, use float32_to_uint64() in the CLGEB handler.

Let's simplify, reworking our handler generation, passing the whole "m5"
register content and not providing specialized handlers for "se", and
reading/writing proper float64 values using new helpers.

Let's rework our macros and simplify. We still need helper functions in
most cases due to the different parameters types.
Next, we'll only have 32/128bit variants for vfi and vfsq, so special
case the others.
Note that for vfsq, the XxC and erm passed in the simd_data() will never be
set, resulting in the same behavior.

other functions, implement it generically for 32bit/64bit/128bit -
carefully taking care of all weird special cases according to the tables
defined in the PoP.

Probably best to fill in all of the values, even if we don't use them right
now. Also, not the fault of this patch, but I don't think this belongs in
include/elf.h. This is linux specific, not some part of the elf specification.

I can most certainly add all currently defined ones for s390x.
We do have the same defines "misplaced" for other archs as well. I'd
like to avoid cleaning that up as part of this series. Thanks!
