Author: Stephan T. Lavavej (StephanTLavavej)
<details>
<summary>Changes</summary>
Found while running libc++'s test suite with MSVC's STL, where we use both MSVC's compiler and Clang/LLVM.
MSVC's compiler rejects the non-Standard extension of zero-length arrays. For conformance, I'm changing these occurrences to `std::array<int, 0>`. Then, in order to avoid disrupting the following code, I'm extracting `.data()` as a pointer.
Many of these files already had `#include <array>`; I'm adding it to the rest.
Finally, I'm adding `-Wzero-length-array` to `params.py` to hopefully prevent future occurrences.
This might need to be clang-formatted, I'll push a commit if so. (I'm still confused as to why some but not all files experience clang-format enforcement.)
