Based on @OfekShochat's https://reviews.llvm.org/D133648 init.c is the primary test for array initialization, but it uses a 32-bit triple, which would lead to an "array is too large" error. Add the new test to array-init.c instead. Fix #57353 Pull Request: https://github.com/llvm/llvm-project/pull/92473
