arm-eabi uses -fshort-enums by default while arm-linux-gnueabi* do not,
like most (all?) other targets, but this test relies -fno-short-enums.
Fix it by forcing -fno-short-enums.

* config/arm/vec-common.md (vcond_mask_): Fix
expansion for MVE.
This patch fixes a problem in arm_expand_vcond() where the result
would be a vector of 0 or 1 instead of operand 1 or 2. The
mve-vcmp-f32-2.c testcase is an update from mve-vcmp-f32.c using a
conditional with 2.0f and 3.0f constants to help scan-assembler-times.

This patch adds support for auto-vectorization of clz for MVE.
It does so by removing the unspec from mve_vclzq_ and uses
'clz' instead. It moves to neon_vclz expander from neon.md to
vec-common.md and renames it into the standard name clz2.

As noted in neon-vhadd-1.c, I couldn't write a test able to use Neon
vectorization with 64-bit vectors: we default to
-mvectorize-with-neon-quad, and attempts to use
-mvectorize-with-neon-double resulted in much worse code, which this
patch does not aim at improving.

Some targets (eg arm-none-uclinuxfdpiceabi) do not support Thumb-1,
and since the testcase forces -march=armv8-m.base, we need to check
whether this option is actually supported.
Using dg-add-options arm_arch_v8m_base ensure that we pass -mthumb as
needed too.

Hi,
As the new test uses -fopenmp, it fails on targets that do not support it.
I've committed the attached patch to skip the test in such cases.

The new test gcc.c-torture/execute/ieee/cdivchkld.c needs fmaxl(),
which may not be available, for instance on aarch64-elf with newlib.
As discussed in the PR, requiring c99_runtime enables to skip the test
in this case.

nce I posted the patch series, I've noticed a regression in
armv8_2-fp16-arith-1.c, because we now vectorize all the float16x[48]_t loops,
but we lose the fact that some FP comparisons can throw exceptions.
I'll have to revisit this patch.
Thanks,
Christophe

dg-do must come before dg-skip-if, this patch fixes this oversight in
these two tests.
Committed as obvious.
