openmp: Avoid ICEs with declare simd; declare simd inbranch [PR93555]
The testcases ICE because when processing the declare simd inbranch,
we don't create the i == 0 clone as it already exists, which means
clone_info->nargs is not adjusted, but we then rely on it being adjusted
when trying other clones.

PR middle-end/93555
* omp-simd-clone.c (expand_simd_clones): If simd_clone_mangle or
simd_clone_create failed when i == 0, adjust clone->nargs by
clone->inbranch.
* c-c++-common/gomp/pr93555-1.c: New test.
* c-c++-common/gomp/pr93555-2.c: New test.
* gfortran.dg/gomp/pr93555.f90: New test.
